Hi,

I think I found the root cause of the problem. sympy's setup.py
has the following line:

import sympy

it is the line triggering everything. I don't know if it calls the already
installed system sympy or the build copy (but I could find out).
The matter is it is reproducible by just opening a python2.6 shell
and typing "import sympy" and you will get the same message.
Try "import mpmath" and you will get the exact same error. This is
because the problem comes from mpmath and in the case of sympy
the copy of mpmath that is shipped with it.

Here I get the

KeyError: 'DOT_SAGE'



installs of 4.6.alpha3 and 4.5.3 both exhibit the error when

ebuild sympy-0.6.6.build compile

is issued.

when I import sympy from a python shell on a machine where sage-4.6.alpha3 is installed but not from one where sage-4.5.3 is installed. However,
