Hi,

I am one of the guys working on getting sage as a system package in Gentoo.
Because a problem I had with mpmath (including the version shipped
in sympy) I discovered that the setup.py file for sympy includes

import sympy

that is it imports itself. I don't think that's right in any way. The only use
I see from the setup.py file is to get sympy's version automatically.

There is one big problem with that. If sympy is already installed in your 
system and known to your installed python the version already installed 
is imported. In short if you have sympy-0.6.6 installed in your system
and you try to install sympy-0.6.7 the version reported in setup.py will be 
0.6.6.

It is clearly what's happening at the moment with the gentoo ebuilds.
