[FIXED] Why does `use GD::Graph::pie;` fail even though CPAN says that GD::Graph::pie is installed and up to date?

Issue

I'm trying to run a script called honeydsum.pl. It is failing a test and insisting I do not have GD::Graph::pie installed. The test that fails is:

unless (eval "use GD::Graph::pie; 1") {
   die "$program_name: please install GD::Graph::pie.";
}

Thus it gives the output:

honeydsum.pl: please install GD::Graph::pie. at ./honeydsum.pl line 65

Where I am confused is that when I check on CPAN it says GD::Graph::pie is up to date:

cpan[5]> install GD::Graph::pie
GD::Graph::pie is up to date (1.21).

I'm not a Perl expert, but is there a reason it would fail the test even if the module is installed?

Output from cpan -D:

~# cpan -D GD::Graph::pie

There was no output from

perl -MGD::Graph::pie -e1

In my /usr/share/ directory I have the following related to perl:

• perl/5.22
• perl/5.22.2
• perl5

I'm not sure what a proper perl installation would have put in this directory.

Solution

The script is using the system perl, but you installed GD::Graph::pie for a perlbrew installation. If you want the script to use your perlbrew perl, change the shebang from

#! /usr/bin/perl -T -w

to

#! /root/perl5/perlbrew/perls/perl-5.20.1/bin/perl -T -w
