Just do a require instead as use is a compile-time construct (as opposed to require which is done run-time) 
require( shift @ARGV );

But as liz notes, that requires munging the module name for any module with a '::' seperator. Better yet, don't load the module at all and just make use of Module::Locate 
use Module::Locate 'locate';

my $path = locate $ARGV[0];
