[phenixbb] Rosetta refine compilation issue Centos 7

[ludovic Pecqueur]

Dear Developers, 

I have a fresh Centos 7 system and after installing Phenix I wanted to compile the Rosetta.refine module. (Rosetta from source version 2015.31.58019)

I have succesfully compiled Rosetta but when I try to build the dedicated Rosetta for Rosetta_refine with rosetta.build_phenix_interface after setting up PHENIX_ROSETTA_PATH and ROSETTA3_DB I get the following error message: 

[XXX at ...]$ rosetta.build_phenix_interface nproc=6
False
scons: Reading SConscript files ...
Running versioning script ... Done. (0.1 seconds)
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
ImportError: No module named site

If you have any idea of what could cause the problem, I would welcome any suggestions.
I updated Phenix and I could compile phenix.rosetta_refine without problems on Centos 6.7.

Thank you very much for your time and help. 

Kind regards, 

Ludovic.
