Here's the first set of patches. This fixes the problems

* root-plugin-gfal is explicitly disabled by passing
  `--disable-gfal' to the configure script in the generated spec
  file.
* More sophisticated algorithm to discover whether man(1) pages
  are compressed before they are moved into a package.   This
  should work for all systems.
* Made the package build depend on XFree86-devel (rather than
  xorg-devel) as I think all X development packages provide that
  capability (sigh, one can not do alternatives in RPM
  dependencies).
* Fixed problem with different names of mysql-devel on various
  systems (thanks to Anders Waananen for fix).
