Basicly I am using QMake here.  I have KDE4 and KDE3 installed.   I would like 
to have a .pri file that I can include and then be able to build 3rd party 
KDE applications.  I actually think your suggestion to make kde-config aware 
of pkg-config installations would be the best fix.  This will become more 
important as KDE 4 becomes released because developers may wish to develop 
against the released KDE 4 and a svn snapshot.   With kde-config knowing 
Since on the off chance you want to develop against older versions of KDE (a 
MUST for 3rd party development) you will  where the pc files reside, it would 
be trivial to switch between the two.

The only reason I would think a proxy for pc would be marginally better would 
be simplicity for the user (since pc support in autocrap afaik needs help 
when you want to do nonstandard things).  I am pretty sure though the cost 
for the gain is not worth it.
