[Numpy-discussion] python 2.4 incompatibility in numpy.lookfor in numpy 1.2.0rc2
Hi,
I was trying to use lookfor on python 2.4 and got an exception with
np.lookfor because of a missing method in pkgutil that was added in
python 2.5.
see the following session
np.lookfor('range')
Traceback (most recent call last):

regenerate)

this works for me and leaves the module unchanged if iter_modules is
available
python 2.4 compatible version is copied from
http://bazaar.launchpad.net/~pauli-virtanen/scipy/pydocweb/revision/386
