From the documentation for use:

Imports some semantics into the current package from the named module, generally by aliasing certain subroutine or variable names into your package. It is exactly equivalent to

BEGIN { require Module; import Module LIST; }

except that Module must be a bareword.

So, given that, we can replace the 'use' with some form of logic structure

BEGIN {
    if ( ... ) {
#        require 'CGI::Carp';
        require CGI::Carp;
        CGI::Carp->import('fatalsToBrowser');
    }
}

alternately, you can place the 'use' within an eval. (but you'll want it inside a BEGIN block, so it runs really early)

As for what to test for, to compare if you're under CGI vs. on a console... I typically test for the existance of $ENV{'SERVER'} or any of the other environmental variables that are set by the webserver when it's running under CGI.

Update: blah...no quotes in require when not giving direct paths to files.
