Dear maintainer,

That first set of patches was obviously misdirected... sorry.

The attached patches port nipype to Python 3 and stop making a Python 2 
module.

However:

* I can't successfully build the package due to the debian/patches/
deb_git_hash. If I leave that in then dpkg-source cannot apply the patches. 
The contents of the orig.tar.gz do not match what is in git for the file 
nipype/COMMIT_INFO.txt so I do not know what was intended here.

* I can't successfully build the package in parallel and I can't figure out how 
to stop parallel building with CDBS. When built with -j4 there seems to be a 
race condition in building the documentation that leads to a FTBFS. It builds 
OK for me with -j1.

regards
Stuart
