Hi Ralf,
It is another Apple object file namespace thing. If you remove the - 
no-undefined flag for darwin then the test will pass, alternatively,  
you can add the -Wl,-flat_namespace flag (though I haven't tested  
this latter, it ought to work).

In my poking about I did:
undefined_setting="-no-undefined"
shared_fails=no
case $host_os,$LDFLAGS in
aix*,*-brtl*) ;;
aix*) shared_fails=yes ;;
darwin*) undefined_setting= ;;
esac
[snip]]
LDFLAGS="$LDFLAGS $undefined_setting -L$deflibdir"

This test looked okay to me. If you want to skip on darwin or remove  
the -no-undefined, up to you.

Thank you,
Peter
