Perl Update in OS X 10.10.5, Cannot Locate Perl Modules

Question

UPDATE: I tried again and realized that perl said that when it tried to load the module, it got a "permission denied" error. So, I just re-ran the script using sudo...and it worked. I guess it must be some sort of permissions changes.

Original:

I just updated OS X to 10.10.5 and suddenly, Perl can no longer locate any of my CPAN-installed modules. Even newly installed modules are not found. I know that the update installed Perl 5.18.2, but even when I explicitly use 5.16, the modules still cannot be located.

The output of perl -V is here:

Any help and suggestions would be greatly appreciated!

I've found the newly installed modules in /Library/Perl/5.18/. — jrg
How can you "explicitly use 5.16"? Wasn't it replaced by 5.18? — ikegami
They don't remove the old versions, so you can point to whichever version you want. — jrg
I can help you with the old version problem, if you want. Start a new question. Provide perl -V from that version. Specify where the modules perl can't find are located. (Search your entire drive for a module you installed if you need to.) — ikegami

Locating them is not going to help. You need to reinstall them anyway. Perl doesn't maintain binary API compatibility between version (though you can safely upgrade to a newer release of the same version).
