If you want to load the module if it is installed (as opposed to deciding
if it is installed without loading it), wrap a require statement in an
eval to catch the error (untested):
unless ( eval { require CGI; 1 } ) {
# not found, do something...
}
You can wrap a BEGIN {} around that if you need the action at compile
time, as in "use".
