Debian: Problem installing PAR::Packer

[jowe]

Running sudo cpan install PAR::Packer gives me the following result:

*** You have extra Perl library paths set in your environment.
    Please note that these paths (set with PERL5LIB or PERLLIB)
    are not honored by perl when running under taint mode, which
    may lead to problems. This is a limitation (by design) of
    Perl, not of PAR::Packer; but some of the problems may
    manifest here during installation.

Running Linux Debian 7.4.0 and Perl 5.14.2.

Has it something to do with the UNIX-style makefile or is an environment variable missing??

I really would appreciate if you could point me into the right direction or is there any hint how to overcome the problem?

Many thanks in advance - Jo

This is odd:

/usr/lib
ln -s libperl.so.5.14 libperl.so

Then PAR::Packer installs via cpan. I would strongly suggest you build your own perl and leave the system one alone, this is fairly trivial (read the update here).

Update: I managed to mess up the code, fixed.

Thanks very much. The 'ln' did it. Once again - many thanks - Jo

[marto]

Glad it worked, that being said please consider installing perl elsewhere and leaving the system perl alone :)

You can save yourself a lot of grief by using the binary packages maintained by Debian instead of trying to install from CPAN if you are going to add modules to the system Perl.
https://packages.debian.org/wheezy/libpar-packer-perl

sudo apt-get install libpar-packer-perl

[jowe]

I tried it. PAR::Packer exists but did not install (Apper) due to an 'invalid format'.

cannot find -lperl

Where is libperl...a? Is it in /usr/lib/perl/5.14/CORE?

[Pizentios]

Like others have said here, messing with the system perl typically isn't a good thing. You can cause many many issues that aren't fun to fix. Using perlbrew or installing the modules using the system's package manager is much safer. However, sometimes the system's package manager is behind quite a few versions, which can be a pain as well.

Personally i enjoy all that perlbrew has to offer.
