I tested apbuild. What I found out that it doesn't need special 
integration (hovewer it's possible). Only need to specify two enviroment 
variables to override the default compilers (CC=apgcc CXX=apg++). I 
compiled kdeadmin/kcron. The results of 'readelf -d kcron':

without apbuild (only relevant parts):

with apbuild:

  0x00000001 (NEEDED)  Shared library: [libc.so.6]

The results are convincing - no unneeded dependencies.
