/tmp/texlive-source-svn58132/texk/kpathsea/tests/cnfline/texmf.cnf
# $Id$
# Public domain. This tiny texmf.cnf is for kpathsea/tests/cnfline.test.

maxpr.kpsewhich=200
othervar=300

As i'm not sure anymore if i really had used the same options while 
testing,
i again did some testbuilds and noticed that without --enable-shared the 
test works.
With --enabled-shared, /tmp/texlive-build/texk/kpathsea/kpsewhich is a 
shell-script/wrapper and not a binary.

I did the debugging from your former answer and compared:

  kdebug:returning from search(aliases) =>

So maybe it's something with this wrapper-script, and the binary 
kpsewhich(when its needed libs and itself is installed) has no problem.
