[Numpy-discussion] numpy distutils log error with easy_install

[Matthew Brett]

Hi,

One of our kind users pointed out an error when using easy_install to
install our package nipy.   I've reproduced it now on a bare package
using numpy distutils and having a trivial extension:

https://github.com/matthew-brett/apkg

To reproduce:

git clone git://github.com/mathew-brett/apkg.git

easy_install apkg

You should get something like this:

Processing apkg
Running setup.py -q bdist_egg --dist-dir
/home/mb312/tmp/apkg/egg-dist-tmp-T5yjuB
Appending apkg configuration to
Ignoring attempt to set 'name' (from '' to 'apkg')

Finished processing dependencies for apkg==0.1
/home/mb312/.virtualenvs/np-1.6.2/lib/python2.6/site-packages/numpy/distutils/misc_util.py:252:
RuntimeWarning: Parent module 'numpy.distutils' not found while
handling absolute import
  from numpy.distutils import log

Note the last error.  All of nipy, scikits-learn and
scikits-timeseries (that use numpy distutils) give this same error on
easy_install.  The error requires the use of an extension in the
package, as in:

https://github.com/matthew-brett/apkg/blob/master/apkg/setup.py#L4

It appears to be benign but it certainly confuses people doing
easy_install.  This is running current numpy master, but the same
occurs with numpy 1.5.1 that I have to hand.

Any ideas what could be causing this?

Cheers,

Matthew
