Description of Problem: In the perl.spec file included with perl-5.6.0-12.src.rpm, there is a typo in the %build section. Currently, the "-Uuselargefiles" is being passed to Configure. It should be "-Duselargefiles" Version-Release number of selected component (if applicable): perl-5.6.0-12.src.rpm Result: The perl rpms included with Redhat 7.1 may not actually support large files (I am unable to test that).

The large files switch is set to "off" to be binary compatible with perl modules compiled against 5.6.0 that shipped with 7.0, which did not ship with large file support, either. Changing this option breaks XS library compatibility.
