Looking at index.py around 188, it looks like pip is reading and
selecting links off this page:

https://pypi.python.org/simple/sympy/

then reverse sorting (by version string) to find the preferred
package. In our case, there is more than one matching package with the
same required version, and the sort by version does not affect the
order of the packages with the same version.

In the case of 0.7.2 the relevant links are in this order:

sympy-0.7.2-py3.3.tar.gz
sympy-0.7.2.tar.gz

so pip selects both, then prefers the first.

In the case of 0.7.3 the links are in order:

sympy-0.7.3.tar.gz
sympy-0.7.3-py3.3.tar.gz
https://github.com/sympy/sympy/releases/download/sympy-0.7.3/sympy-0.7.3-py3.3.tar.gz#md5=
c6343a8eb1ab9a9741b3a3bba02a0eeb

and it finds sympy-0.7.3.tar.gz first and prefers that.

Can you reorder the links on the page?  I suspect it will fix it,

Cheers,

Matthew
