Turns out this was an Anaconda-specific problem: Py_SetProgramName() resolves the prefix to "/opt/anaconda1anaconda2anaconda3". I sent a post to Anaconda public support forum (anaconda at continuum.io) to find out whether it can be solved without setting $PYTHONHOME or calling Py_SetProgramName() with a full path.

Thanks for your kind help,
