Description
Scipy failed to build today when using a self-compiled version of numpy, being in a folder that had some whitespaces in it. I could track the issue back to numpy's parse_flags method, which fails if there are whitespaces in the directory.
The following 5 lines of python code will allow to reproduce the issue:
from numpy.distutils.npy_pkg_config import parse_flags
d = parse_flags("-L/my_folder/without_whitespaces/in_it")
print d
d = parse_flags("-L/my_folder/with whitespaces/in_it")
print d
