Hi Paul,

Thanks for sharing this. It seems there is no straightforward solution for this 
kind of issue.

It seems there is some kind of intersection between epel and pip. Take 
TurboGears for example. epel7 does provide the rpm of TurboGears but doesn't 
guarantee it could be installed (epel5 didn't have this issue, not sure for 
epel6). This is also applicable to TurboGears2 on epel7 which is supposed to be 
not old. Then I am not sure why we have TurboGears on epel7? I thought all the 
rpms on epel were supposed to be able to be installed, but I might be wrong.

I have just installed TurboGears using pip (current TurboGears on pip is 
version 1.5.x). Probably  we consider migrate our project to TurboGears 1.5.x 
or even TurboGears2.

When you use PIP make sure you also virtual-env for the application python 
libraries and environment. This will allow you to install the PIP packages into 
a isolated python environment for just that application and not impact the 
'system' python environment.

http://stackoverflow.com/questions/5844869/comprehensive-beginners-virtualenv-tutorial
Alternatively you could package the python libraries to RPM yourself if you 
have to deploy the same setup to many systems (at that point I assume you would 
be using a tool like chef or puppet, so hand building RPMs might be quicker 
than rolling out a virtual-env to all your servers).

For all packages which can be found from pypi, I'd recommend using pip to 
install them.

I don't know the plan, maybe the missing packages will never get into EPEL7.
