Dependency chaos. Some packagers have started with adding
Requires: %{_libdir}/pkgconfig
instead of the good old "Requires: pkgconfig". Not only is this dependency
expensive -- the filelists metadata must be loaded and parsed -- it doesn't
work correctly either, because
1) package "pkgconfig" is not multilib'ed, so e.g. pkgconfig.i386 is
not available in the x86_64 repo, and hence nothing provides the
/usr/lib/pkgconfig directory, (and it would be a broken dep) but
2) a couple of other packages include %_libdir/pkgconfig by accident,
which violates the packaging guidelines. Namely:
openchange-devel 499655
ipod-sharp-devel 499658
sane-backends-devel 499659
libXScrnSaver-devel 499660
freetype-devel 499661
anthy-devel 499663
Since these are multilib'ed, a dependency on /usr/lib/pkgconfig
doesn't pull in pkgconfig.i386 but one of these -devel packages
instead.
[...]
Conclusively, neither "Requires: %{_libdir}/pkgconfig" nor
"Requires: pkgconfig%{_isa}" will work as expected.

Is it correct to use:
Requires: pkgconfig
...
%files devel
%defattr(-,root,root,-)
%{_libdir}/libpst.so
%{_includedir}/%{name}-@LIBPST_SO_MAJOR@/

These days RPM automatically adds a dependency on /usr/bin/pkg-config.
So in most cases where a package provides a *.pc file it should not be
required to manually add the runtime dependency.

"These days" translates to "Fedora >= 11". Packagers who push
mass-dist-updates
should not eliminate their manual "Requires: pkgconfig" yet.
The /usr/bin/* file entries can be found in the primary metadata, so
dependencies on them are not as expensive as other file paths.

That is why I enclose the pkg-config related lines in a conditional
block that evaluates to true only for Fedora 9 and Fedora 10.

Meanwhile, pkgconfig is being multilib'ed. For F-11 and F-12. I see
pkgconfig.i386 in the x86_64 repo, and that means one could require
pkgconfig%{?_isa} where automatic .pc file dependencies don't pull it in.
