Description Michael Schwendt 2009-02-10 10:33:10 UTC 
uuid-devel really ought to "Requires: pkgconfig"
instead of depending on %_libdir/pkgconfig. The latter requires
package resolvers to download and parse the huge filelists instead
of just the primary metadata.

$ rpm -q uuid-devel
uuid-devel-1.6.1-3.fc9.i386

It does a similar thing in the -php and -pgsql subpackages.
Inflation of file dependencies will make dependency resolving
in Fedora slower and slower until we are forced to fight such
dependencies with strict guidelines. Please avoid them.

If you have strong doubts that a needed directory will stay in
the same package, add a safety-check to your %prep script.

"Requires: %_libdir/pkgconfig" doesn't work, since it's a hidden broken dep. For example, pkgconfig.i386 is not made available in the x86_64 repo, so nothing provides /usr/lib/pkgconfig, and you don't get pkgconfig.i386 with a dependency on the path. It just seemed to work because other -devel packages included and provided %_libdir/pkgconfig because of packaging bugs. Using "Requires: pkgconfig%{_isa}" was base on the assumption that pkgconfig is multilib'ed, but actually the 32-bit pkgconfig is not available on 64-bit multi-lib platforms.
