Problem building koffice on an 64bit opensuse 11.0

(Sent that before but with my other non subscribed account. seems like it 
didn't get through so here once again. sorry if double posting. )

I hate to say it but it is probably a good idea to ignore my ramblings in such 
cases for some days. 

I think i completely understand the problem now.

We use --fatal-warnings which means that warning "skipping incompatible 
/usr/lib/libGL.so when searching for -lGL" becomes an error and the linker 
stops. If i remove that it links successfully.

So the questions is who triggers the warning? The problems is GraphicsMagicks 
pkgconfig file. The package i have installed here has the following snippet on 
the Libs line: "-l/usr/lib64 -l/usr/lib -l/usr/lib64 -l/usr/lib". This is 
absolutely unnecessary because the linker would use the correct directory 
anyway. So here is the first bug imho.

pkgconfig tries to help and removes the two "-l/usr/lib64" arguments because 
this is the "system lib dir" and it is pointless to provide it. You can see 
that with "pkg-config GraphicsMagick --debug --libs". It removes one of the "-
l/usr/lib" too because it's provided two times. I think we could say this is 
bug number 2. it should remove /usr/lib on 64 bit systems and /usr/lib64 on 32 
bit systems when it find them. Is there any chance you link against libs from 
/usr/lib on a 64 bit system or vice versa?

So the "-l/usr/lib" finds its way into the linker command and i get my error.

I just fixed the GraphicsMagick.pc file and everything compiles smoothly. 
Anyone an idea where to file a bug? With opensuse or GraphicsMagick?
