Ah yes, a theory is as follows: geninterp tries to add pypy/lib/ in
front of sys.path so that when it executes app_array.py directly on top
of CPython the modules over there get found (that's a bit of a hack,
really). But in CPython, 'import struct' always pick up the built-in
struct module if it is really a built-in and not an extension module.
So the hack may fail if we're running on top of a CPython with a
built-in struct module.
This could be solved with a counter-hack: try adding a file
pypy/module/array/struct.py with the content:
from pypy.lib.struct import *
