Chris answered your first question, but not this one. You can check in the
%INC hash. The keys use Unix file name semantics. For example:

#!perl
use LWP::UserAgent;

print "existsn" if exists $INC{"LWP/UserAgent.pm"};

The hash element contains the full MacOS path to the file.

Print out all of %INC if you want to see how much stuff your favorite
module loads.
