I found the problem. The version of pkgconfig in SuSE Linux
Enterprise
Desktop 10 SP1 has the following entry in
/usr/share/aclocal/pkg.m4:
m4_pattern_forbid([^_?PKG_[A-Z_]+$])
Basically, trying to define any variables of the form
"PKG_BLAH_BLAH_BLAH" in a configure.ac macro file
is a no-no. I've
changed all instances of PKG_REQUIRES in my source tree to
PACKAGE_REQUIRES. If you want to include this change in the
trunk so
this issue doesn't hit any other Linux users that happen to
have this
pkgconfig setup, here's the diff:
