Well, this is strange....  ASE is pure python, so it should not be
possible to cause a segfault only from ASE.  It must be either in an
external library like NumPy, or in the Python distribution.  Most
likely the former, particularly the installation is not provided by
the BSD distribution.

Will numpy work?  Can you import ASE without trouble?  It appears to
crash quickly, before doing much of anything.
