For quite a time, I have a problem with perl on my system. I don't have the permissions to install or even execute perl scripts as a normal user. IMHO this shouldn't be the default behaviour, but I can't say when and where this changed on my computer.
Examples:
.-(~) - (strix@tirion)-
`--> id
uid=1000(strix) gid=100(users) groups=100(users),7(lp),10(wheel),50(games),90(network),91(video),108(vboxusers),150(wireshark)
.-(~) - (strix@tirion)-
`--> cpan
Can't locate App/Cpan.pm: Permission denied at /usr/bin/core_perl/cpan line 9.
BEGIN failed--compilation aborted at /usr/bin/core_perl/cpan line 9..-(~) - (strix@tirion)-

I'm Gonna ask the obvious. Do the scripts you made have executable permissions set?
Do all scripts complain about permissions( hello world for example) or just some particular ones?
Because if its the latter, the script might be trying to invoke some commands that actually need super user privileges regardless of the invocation in perl?

Okay, first of all: I'm an absolute Noob when it comes to Perl. I only use perl in scripts I downloaded or which are part of a package.
So to answer you first question, yes:
lrwxrwxrwx 1 root root 18 Jul 4 14:53 /usr/bin/perl-rename -> vendor_perl/rename*
-r-xr-xr-x 1 root root 13K Jul 4 14:53 /usr/bin/vendor_perl/rename*
-r-xr-xr-x 1 root root 241K Nov 16 14:26 /usr/bin/vendor_perl/exiftool*The scripts complain, as soon as they use perl modules, e.g. almost always:
A simple Hello World works:
`--> cat hello.pl
#!/usr/bin/perl
print "Hello World\n";
`--> ./hello.pl
Hello WorldBut most perl packages do not:
exiftool:
`--> exiftool

BEGIN failed--compilation aborted at /usr/bin/vendor_perl/iptab line 6.Edit:
the perl modules do exist:
`--> ll /usr/share/perl5/vendor_perl/Net/IP.pm
-r--r--r-- 1 root root 73K Nov 28 2012 /usr/share/perl5/vendor_perl/Net/IP.pmAre these the correct permissions? And why can't I install any perl modules as user?
