Compiling qcad using clang++ under current

[mike]

Hi,
compiling the QT4 application cad/qcad using clang++ works for me on freebsd 
current amd64 r254593 but fails on the package cluster.

Fail-log:

clang++: error: linker command failed with exit code 1 (use -v to see

...

The strange thing is that the debug object where compiled using -fPIC !


The relevant compiling do work for me without errors and using the same build 
environment:

Can anyone imagine whats different on the package cluster?

Thanks in advance!
