This is evil, but would work. Reinstall the module you wrote with a version = version + 0.01 . Look at what it says it's doing. (Eg, copying file asdf.pm to /usr/local/perl5/5.8.0/site_perl/asdf.pm or simliar) As an appropriate user, rm -rf those files it says it's copying (if all you're doing is pure perl module). If you used h2xs binding to a library... then you're beyond my knowledge and I wish you good luck... :) Cheers.
