That's because the assigment of $perl_module doesn't happen until runtime, while the use happens at compile time.

You basically have two options:

Move assignement to compile time 
my $perl_module;
BEGIN {$perl_module = shift};
eval "use $perl_module";

Move loading of module to runtime 
(my $filename = "$perl_module.pm") =~ s#::#/#g;
require $filename;
$perl_module->import;

The first has the disadvantage that you need to eval a string. If you can't trust the parameter input, that may be a security issue.

The latter has the disadvantage that you must convert the module name to a filename. But you need the original module name to be able to do the import().

Hope this helps.
