Installation fails with old pip

[Anatoly Scherbakov]

Hello.

An outdated pip (I had 1.4.1) on python 2.7 might fail installing memprof with the following message:

Installed venv/lib/python2.7/site-packages/Cython-0.22-py2.7-linux-x86_64.egg
Processing dependencies for Cython
Finished processing dependencies for Cython
Traceback (most recent call last):
  File "<string>", line 16, in <module>
  File "venv/build/memprof/setup.py", line 38, in <module>
    class md_easy_install(easy_install):
TypeError: Error when calling the metaclass bases
    module.__init__() takes at most 2 arguments (3 given)
----------------------------------------
Cleaning up...

Fix is to update pip saying

pip install -U pip

Thank you for the great library!

Hello Anatoly,

The setuptools/easy_install/pip ecosystem is a bit of a nightmare.

You can also find memprof in many Linux distributions (Arch, Debian,
Ubuntu, etc.) and macports. It should be easier to install from there
;-)

Thanks for your feedback, it will help others.
Jose.
