Pyinstaller --onefile warning pyconfig.h when importing scipy or scipy.signal

Question

This is very simple to recreate. If my script foo.py is:

import scipy

Then run:

python pyinstaller.py --onefile foo.py

When I launch foo.exe I get:

WARNING: file already exists but should not: C:UsersusernameAppDataLocalTemp\_MEI86402Includepyconfig.h

I've tested a few versions but the latest I've confirmed is 2.1dev-e958e02 running on Win7, Python 2.7.5 (32 bit), Scipy version 0.12.0

I've submitted a ticket with the Pyinstaller folks but haven't heard anything yet. Any clues how to debug this further?

You can hack the spec file to remove the second instance by adding these lines after a=Analysis:

for d in a.datas:
    if 'pyconfig' in d[0]: 
        a.datas.remove(d)
        break
