Bug ID: 1033018
Summary: syntax error in /etc/profile.d/perl-homedir.csh
(perl-local-lib/perl-homedir)
Product: Fedora
Version: rawhide
Component: perl-local-lib
Severity: low

External Bug ID: CPAN 85667
+++ This bug was initially created as a clone of Bug #1032195 +++
Syntax error in /etc/profile.d/perl-homedir.csh
---Steps to Reproduce---
* Install perl-homedir
* Create a user with csh as login shell
* login with that user
The file /etc/profile.d/perl-homedir.csh, contained in perl-homedir,
contains a syntax error.
The command "eval `perl -Mlocal::lib`" fails with "Bad : modifier in $ (/).".
The processing of any login scripts stops at that error, resulting in an
incomplete environment for the user.
Fyi ...
.... looks like this is caused by missing {}:
ls3814:db2lin 8> perl -Mlocal::lib
setenv PERL_LOCAL_LIB_ROOT "$PERL_LOCAL_LIB_ROOT:/db2/db2lin/perl5";
setenv PERL_MB_OPT "--install_base /db2/db2lin/perl5";
setenv PERL_MM_OPT "INSTALL_BASE=/db2/db2lin/perl5";
setenv PERL5LIB "/db2/db2lin/perl5/lib/perl5:$PERL5LIB";
setenv PATH "/db2/db2lin/perl5/bin:$PATH";
ls3814:db2lin 9> setenv PERL_LOCAL_LIB_ROOT
"$PERL_LOCAL_LIB_ROOT:/db2/db2lin/perl5";
Bad : modifier in $ (/).
ls3814:db2lin 10> setenv PERL_LOCAL_LIB_ROOT
"${PERL_LOCAL_LIB_ROOT}:/db2/db2lin/perl5" ;
# no error
[...]

Thank your for this bug report and a suggestion how to fix. Unfortunately, this
is not enough.
If PERL_LOCAL_LIB_ROOT is not set, then tcsh will bail out with undefined
variable and the variable will not get set:
[test@rhel-7-0 ~]$ echo ${?PERL_LOCAL_LIB_ROOT}
0
[test@rhel-7-0 ~]$ setenv PERL_LOCAL_LIB_ROOT
"${PERL_LOCAL_LIB_ROOT}:/home/test/perl5" ;
PERL_LOCAL_LIB_ROOT: Undefined variable.
[test@rhel-7-0 ~]$ echo $?
1
[test@rhel-7-0 ~]$ echo ${?PERL_LOCAL_LIB_ROOT}
0
This is a know issue to the upstream
<https://rt.cpan.org/Public/Bug/Display.html?id=85667> with no ratified
solution yet.

Due to CSH limits on subcommand substitution and parsing if-then-else
statemens, appending to a variable FOO can be achieved this way:
test 1 == ${?FOO} && setenv FOO "a:${FOO}" || setenv FOO "a";
