Are you ~sure~ this does what you want it to? Require behaves differently if you feed it a bareword or a variable. (Maybe this was the reason for catfile?)

http://perldoc.perl.org/functions/require.html

use strict;
use warnings;

my $x="x";
my $module = $x . '::' . $x;

print "$module\n";
eval { require $module; };

The eval block needs some finetuning to actually do what you want it to. (Do something if require succeeds, do something else if require fails. Recommendation: Use Try::Tiny and stop worrying about all the ways eval / $! / $_ can go wrong. 
use strict;
use warnings;

use Try::Tiny;

my $x="x";
my $module = $x . '::' . $x;

try {
  require $module;
  print "Found module $module.\n";
}
catch {
  print "Failed to find module $module!\n";
};
