The source RPMs for these modules can be found in the SRPMS directory. The SRPMS are designed to build under Red Hat Linux 9, Red Hat Enterprise Linux 3 & 4, Fedora Core 1 to 4, but may also work for other Red Hat-based distributions, such as Red Hat Linux 8.0, Whitebox Linux etc. These distributions aren't tested in any way though.
Modules included in Fedora Extras are not usually built here for Fedora Core 4. Moreover, the modules available here may include dependencies on packages in Fedora Extras, so adding the extras repository to your yum configuration would be a good idea if you intend to use these packages.
If you're here for the Mail::SPF::Query RPM, you may also be interested in the sendmail-milter-spf RPM in the mail directory.
HTML::Tidy is a replacement for HTML::Lint, and requires tidy, which can be found in the websrv directory.
If you have any queries or problems with these RPMs, please contact the packager, Paul Howarth <paul@city-fan.org>
