 I'm running Perl 5.6 and recently re-compiled Apache 1.3.12 and mod_perl 1.24

 errors:
 
 -
 Subroutine handler redefined at 
 /usr/local/lib/perl5/site_perl/5.6.0/i686-linux/Apache/Registry.pm line 27.
 Subroutine compile redefined at

 They seem to be focused on Registry and DBI. When I remove the startup.pl
 file from httpd.conf, I get no errors.
 
 Here's the cgi-perl section of httpd.conf:
 
 -
 Location /cgi-perl/
  SetHandler perl-script
  PerlModule Apache::Registry
  PerlHandler Apache::Registry::handler
  PerlModule Apache::DBI
  PerlInitHandler Apache::StatINC
  Options ExecCGI
  PerlSendHeader On
 /Location
 -
 
 Here's part of my startup.pl file:
 
 -
 use Apache::Registry ();
 use Apache::Constants ();
 use Apache::Sandwich ();
 use Apache::Include ();
 use DBI ();
 use Apache::DBI ();
 -
 
 Should I not duplicate these modules and just have all of them in the
 startup file?

from the ApacheDBI-0.87 README:
  " If you plan to use persistent database connections, there is only one thing
  to do: add the following configuration directive to conf/httpd.conf or to
  your startup.pl:
 
   PerlModule Apache::DBI# this comes first !!
     # other modules using DBI
 
compare to your startup.pl.
might be relevant

Right.  The 'use' statements and 'PerlModule' directives are doing the
same thing, so you only need one or the other.  But it strikes me as odd
anyway that it's actually loading it twice though, because Perl should
see that it's in %INC and not try to load it again.  So there might
indeed be something fishy here, even though it's easily fixable.

By the way, 'PerlModule' directives are traditionally put at the top
level of the config file, outside any directive blocks.  They always
affect the global server anyway, not just the config section they're in.
So it's a bit misleading to put them in a config section.
