I can easily reproduce this warning message with 'pkg-config xxx',
xxx is anything can not be found in 'pkg-config --list-all'.
My system has nearly no response (console, network, etc.) after that.

 From that I find 'gnome-config' is symbolic-linked to 'pkg-config'
on my system(!). When 'pkg-config' can't find anything about 'xxx',
it calls 'gnome-config', and 'gnome-config'('pkg-config') calls
'gnome-config'('pkg-config') calls...:)
