Travis fails to install pymongo under PyPy 1.2

[neithere]

Everything is perfect locally on PyPy 1.2.1 but an obscure error in Travis (e.g. https://travis-ci.org/neithere/monk/jobs/15173648):

$ python --version
Python 2.7.3 (f3423a62cd09, Nov 12 2013, 16:09:06)
[PyPy 2.2.0 with GCC 4.6.3]
$ pip --version
pip 1.4.1 from /home/travis/virtualenv/pypy/site-packages (python 2.7)
$ pip install -r requirements/devel.txt --use-mirrors
Downloading/unpacking pymongo==2.6.3 (from -r requirements/basic.txt (line 1))
RPython traceback:
...
Fatal RPython error: KeyError
/home/travis/build.sh: line 147: 1273 Aborted pip install -r requirements/devel.txt --use-mirrors
The command "pip install -r requirements/devel.txt --use-mirrors" failed and exited with 134 during install.
Your build has been stopped.

Possible solutions:

• wait for a more recent version of PyPy
  • and have failed builds all the time? no, thanks.
• contact Travis team and/or try installing PyPy 1.2.0 locally and dig into that stuff
  • don't care & no time

Possible workarounds:

• drop support for PyPy
  • despite 90% the core of the library works fine? bad idea.
• do not test the MongoDB extension under PyPy
  • how to setup the pypy env in Travis? doesn't seem to support per-env configuration like tox
• do not test the MongoDB extension at all in Travis CI
  • still can test it locally, OK
  • monk.mongo → monk.ext.mongo
  • requirements/basic.txt → requirements/ext.txt (skip it in CI)
• only test PyPy locally; do not include it in Travis
  • this is the simplest way.

Workaround implemented, closing. May reopen if something changes on Travis side.
