more on kde4 build

For the sake of trying to generate discussion i was able to compile kdecore on 
panther with some tiny modifications. For some reason bksys didn't detect 
sys/mman.h nor net/if.h, after some hack-ish modifications kdecore builds. 
Now i'm getting the following error:

scons: *** Source `dcop/libkdeinit_dcopserver.la' not found, needed by target 
`build/dcop/dcopserver'.  Stop.
scons: building terminated because of errors


Is this because of an scons dependency error? This doesn't seem like its mac 
related at all. 

thanks,
