If EXPR is a bareword, the require assumes a ".pm" extension
and replaces "::" with "/" in the filename for you, to  make it
easy to load standard modules.  This form of loading of modules
               does not risk altering your namespace.

Unfortunately your require does not use a bareword. You could say 
something like

$var = "$module.pm"; eval { require $var; }

or perhaps easier to follow, but less efficient

eval "require $module;"

By the time the require is hit in the second case, it appears that 
$module has become a bareword - for this reason you need to be 100% 
certain that $module is safe!

Cheers,

Luke
