building of dcopserver fails

[Holger Schröder]

Hi,

i tried to build kdelibs on linux with scons version 0.96.91. scons configure 
went fine, but when i tried to build with "scons", the following error 
happened:

holger at gentoo ~/svn/trunk/KDE/kdelibs $ scons
scons: Reading SConscript files ...
Checking for libz... (cached) no
libz not found (mandatory).
Checking for libpng... (cached) no
libpng not found (mandatory).
Checking for libjpeg... (cached) no
libjpeg not found (mandatory).
Checking for libagg... (cached) no
scons: done reading SConscript files.
scons: Building targets ...
scons: *** Source `dcop/libkdeinit_dcopserver.la' not found, needed by target 
`build/dcop/dcopserver'.  Stop.
scons: building terminated because of errors.
holger at gentoo ~/svn/trunk/KDE/kdelibs $


can somebody give me some hints what is wrong, and where i should search to 
fix it ?

regards, Holger
