Thanks. Very informative. For the particular module the only thing I could find that was "different" after the install was the addition of an empty directory
I have not been able to do a test with a t directory present. Someone on this forum suggested that I might be missing something in my install because I have Perl 5.6 that came with Mac OS 10.2.x. For the couple of module installs I have done I just skipped the step and everthing seems to work fine.
