Instead of being critical, maybe you could have invoked the FAQ? From
perlfaq8:
How do I add a directory to my include path (@INC) at runtime?
Here are the suggested ways of modifying your include path:
the PERLLIB environment variable
the PERL5LIB environment variable
the perl -Idir command line flag
the use lib pragma, as in
use lib $ENV{HOME}/myown_perllib;
The latter is particularly useful because it knows about machine

dent architectures. The lib.pm pragmatic module was first included
with the 5.002 release of Perl.

Add directories to @INC
I see that there are a lot of people wanting to know how to add directories to their @INC permanently. I accomplished this by adding the following line to the end of my startup.pl file: push(@INC, Put path to directory here); Restart apache and you should be good to go! Hope this helps.

Re: Add directories to @INC
Lee Conine am Montag, 26. März 2007 16:03: Hello (just noted Tom Phoenix's answer with the hint to perlfaq8 after writing, but sending anyway...) I see that there are a lot of people wanting to know how to add directories to their @INC permanently. I accomplished this by adding the following line to the end of my startup.pl file: push(@INC, Put path to directory here); This appends the new library path to @INC. The usual method however is to prepend it to @INC, so the added paths are searched first. That would lead to unshift @INC, 'Put path to directory here'; Which is better expressed by (see perldoc lib) use lib 'Put path to directory here'; Since the startup script unter mod_perl is also used to preload modules - including your own, located in nonstandard paths - a better place to put it is the beginning of the startup script, as you usually put use libs at the beginning of non-mod_perl scripts and modules. And there is a PERL5LIB env variable too that can be populated with additional library paths and exported, f.e. export PERL5LIB=/opt/osf/lib:/opt/smf/lib:/opt/my_perl/lib so you don't have to change scripts or modules (by placing use libs in it).

Someone (including me) has mentioned many times,this couldn't work.
You should:
BEGIN {
unshift @INC, 'Put path to directory here';

RE: Add directories to @INC
Page 300 of the Camel 3rd ed says: any modifications to @INC need to occur at compile time...You can do this with the lib pragma described in Chapter 31 or with a BEGIN block. I think what our colleague meant by reinstalling Perl is that doing so will enable you to tell Perl where to look for modules every time it compiles and executes a program, rather than having to explicitly modify @INC in-program. I have no idea about -I switches and such, I bow out gracefully to the in-house gurus there. =) cheers, nathanael -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

There are a number of ways to *update* @INC, but I know of no way to
permanently *change* it. I think you're looking at a reinstall if you
really, really need the latter.
You can use -I as you mentioned; you can also set $PERLLIB or $PERL5LIB
as in
bash-2.05a$ env PERLLIB=/tmp/perllib PERL5LIB=/tmp/perl5lib perl -V | tail -15
Characteristics of this binary (from libperl):
Compile-time options: USE_LARGE_FILES
Built under freebsd
Compiled at Jul 4 2002 23:57:31
%ENV:
PERL5LIB=/tmp/perl5lib
PERLLIB=/tmp/perllib
@INC:
/tmp/perl5lib
/home/davidtg/local/lib/perl5/5.6.1/freebsd/i386
/home/davidtg/local/lib/perl5/5.6.1
/home/davidtg/local/lib/perl5/site_perl/5.6.1/freebsd/i386
/home/davidtg/local/lib/perl5/site_perl/5.6.1
/home/davidtg/local/lib/perl5/site_perl
(note that PERL5LIB overrides PERLLIB; try the above without PERL5LIB to
see the difference); you can also 'use lib' as in
bash-2.05a$ \
perl -e 'use lib (/tmp/perllib,/tmp/perl5lib); \
foreach (@INC) { print $_\n }'
/tmp/perllib
/tmp/perl5lib
/home/davidtg/local/lib/perl5/5.6.1/freebsd/i386
/home/davidtg/local/lib/perl5/5.6.1
/home/davidtg/local/lib/perl5/site_perl/5.6.1/freebsd/i386
/home/davidtg/local/lib/perl5/site_perl/5.6.1
/home/davidtg/local/lib/perl5/site_perl
.
if you prefer to depend on the script instead of on the environment;
there are probably other ways as well :-)
