Well, no. That one didn't work. I had to be specific about where
CGI::Carp was installed to get it to work:
use lib '/home/user/.cpanm/work/1512448551.26554/CGI-4.38/lib';

I've read about those, but I'd rather not jerry rig this install just
to get it to work. I've been using perlbrew on my Mac (with 5 different perls)
for years without incident, so that's why I'm at a loss as to what's happening
on this VPS. Maybe I should just cut my losses, delete everything, and start
over. I just hate doing that after spending so much time on something. It's
like admitting defeat and giving up. ;)
I just thought to compare the install on my Mac with the one on the VPS
and the binaries of perlbrew are exactly the same, but the binaries for
patchperl and cpanm are wildly different from each other. Are these customized
during installation for the platform that running? If not, would it be safe to
copy my known good copies over to the server (Mac vs Linux)?

Right, so that's your 500 error. But you added the same line in the
original (before the use Carp line?) and it *didn't* fix the problem? Can
you sym link the .cpanm dir under one of those @INC dirs. Hm, there's
also an PERL5LIB env var you can set to add libraries (maybe in the
webserver config).

That's what I thought. Shouldn't "cpanm install Module::Name" do that on it's own? There's only one perl install and one alias, and the alias is selected. Running "perl -v" returns version 5.26.1 so how can I get perlbrew set to install in the current installation?

perlbrew and modules
I've run into another strange problem that I don't understand. Running the script below produces the output "Perl v5.26.1". However, if I add the line: use CGI::Carp qw(fatalsToBrowser); it produces a 500 error. On the shared server, this worked as it should, with 'fatalsToBrowser' showing any errors. But the VPS is just backwards - adding it crashes the script! This actually happens with any module and, yes, they are installed: > cpanm install CGI::Carp install is up to date. (0.01) CGI::Carp is up to date. (4.38) I have been fighting with this VPS setup for almost 2 weeks now just to get a functioning modern Perl environment and I'm about at my wits end. It shouldn't be this hard. I'd appreciate any help.
