Dear all,

please apologize if these are very stupid questions.

We have a couple of catalyst web apps running under apache/mod_perl,
and we usually test the apps during development using the
script/myapp_server.pl script.

I'd like to test the upcoming release, to make sure everything runs
smoothly and check everything well in advance of a future upgrade of
Catalyst::Runtime on our production servers.

So I've downloaded the most recent version (5.89002) and installed it
on a local prefix ($HOME/lib).

Question 1: how to I tell my local checkout of the web app to use
$HOME/lib/share/perl/5.10.1/Catalyst.pm instead of the system's

I've edited myapp_server.pl and added
use lib "/home/fernan/lib";

but upon firing the server using myapp_server.pl, I still see: myapp
powered by Catalyst 5.80031

Question 2: I'm at a loss with regards to PSGI, Plack et al. I've read
the docs at http://plackperl.org/, but I'm still not figuring our what
this is all about. Should I care? Would this affect how I'm currently
deploying my catalyst apps (apache/mod_perl)? Should I change (e.g.
for better performance)? I'd appreciate if someone can explain in one
or two sentences what plack/psgi is and/or why I should care, or
perhaps point me in the right directions?

Thanks a lot.

And as always, many thanks for such a great framework!
