[cctbxbb] Boost Import Error

[Magnus Andersson]

Hi Luc,

The problem is I have a macports python build that contains all the rest of the modules that I import in this script. Because cctbx is not included in macports I have a separate build for this. Hence I need to call my script as:

/opt/local/bin/python2.7 script.py

I have set the PYTHONPATH in the bash shell:

export PYTHONPATH=/Users/magnus/Downloads/cctbx_sources:/opt/local

But, it's not working. Any suggestions how to deal with this?

Thanks,

Magnus
