You mean ../lib, right?

There's no problem with that at all (caveats given below), but do you have a
specific reason for doing it that way?

This isn't much about the CWD, it's about setting the right @INC, which is a
problem related to perl (and pretty much any programming language) as a
whole. You can run the app from anywhere, as long as you tell it where to find
the libs it needs. If you used the standard scaffolding script, that should be
lib/ under your MyApp dir, plus the site_perl libs (which are hard-coded into
@INC by the perl binary in most cases). If you're concerned about loading
unexpected modules, sanitize @INC before you use() anything. Catalyst tries to
make a few guesses as to what @INC should be, and the doc examples try to
match those assumptions, but there's no way it can catch all the possible
scenarios, so if for some reason you decide to do something different than
what's doc'ed, you'll need to adjust the environment accordingly.

I'm not exactly sure about the specific motivation for that change, but
script/myapp_fastcgi.pl is just a perl source like any other, adjust @INC
before running it (via PERL5LIB, -I, etc.) and you'll be fine.
