pkg-config mysticism regarding Requires.private

Ah... I'm guessing it's because one was built with --enable-indirect-deps ... sorry for the noise ...

It seems that xterm has some trouble building with the recent libXaw and libXft changes which move libs into Requires.private ... but that is an issue with xterm's build system (it was using API from libXmu and fontconfig and only picking up those links from xaw and xft's 'pkg-config --libs').

http://cgit.freedesktop.org/xorg/lib/libXft/commit/?id=8751e341bcc29952b4603e18767ab994653c6b01
http://cgit.freedesktop.org/xorg/lib/libXaw/commit/?id=b6750449f32c07fe277146b55a9f988bfaa3e0d2

Why was the change to remove xmu from xaw7.pc not also done for xaw6.pc?
