[Catalyst] Newbie DB Schema/Moose Problem

Fri Mar 16 14:22:08 GMT 2012

Scott,

I recall seeing this error before, and my gut feeling is you don't have com=
patible versions of the metioned libs. =A0A bit of google search gets me:

http://lists.scsys.co.uk/pipermail/catalyst/2011-December/028039.html

Which suggests some approaches.

However one thing I really recommend is to avoid using your 'system perl' (=
installed globally under /usr/bin). =A0This is really going to put you in a=
 world of confusion. =A0The community best and supported practice for devel=
opment is to install a local perl using perlbrew and keep you dependency ch=
ain clean.

Here's some docs:=A0http://learn.perl.org/installing/

I realize it may feel like an un-needed step to install a user level Perl f=
or development, but believe me when I say it will make your life easier. =
=A0Following this method I very seldomly have trouble installing stuff from=
 cpan.

John
