in reply to Checking to see if a particular Module is installed

punkkid's answer is close, but doesn't quite do it if the use statement doesn't return a true value. For example, perl -e "eval 'use CGI' or die" dies. The correct way would be 
my $package = "GD";
eval "use $package; 1" ? gd_stuff() : alternate_stuff();

    Slightly simpler: 
    eval 'require GD';
if ($@) {
  # problems with GD, fall back to non-GD
} else {
  # we have GD, go for it!
}

    There's no point in using use, because you can't affect the compile-time imports at runtime if it's not there!
