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 Fedora Core 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.
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>
