bug#55669: python-peachpy is broken

[Sebastian Gibb]

Hi,

the python-peachpy package fails to build in the current available version
python-peachpy-0.2.0-1.906d578, see
http://ci.guix.gnu.org/build/851814/details

Please find the error message below. While I don't understand python I believe
the problem is fixed upstream with the following commit:
https://github.com/Maratyszcza/PeachPy/commit/eaa2eaef5e4f00bc61d0bc9dafbfda13518c7c57

It would be great if the python-peachpy package could be updated to the latest
upstream version.

Thanks in advance,

Sebastian
