OpenMPI with pgi CDK 147

Hello, i am not able to recompile openmpi-1.7.5 sourcecode with pgi 147.
It turns out following error:
module load compilers/portland/pgi64/2014
[root@newl2 openmpi-1.7.5]# pgcc --version

pgcc 14.7-0 64-bit target on x86-64 Linux -tp sandybridge

./configure exists without error.

make gives following:

thanks,
Arman.

This same thing happens with PGI-15.4 and OpenMPI-1.8.5.

export CPP=cpp and rerunning configure fixes this.
