As an aside, if two upstream packages include another upstream
package (e.g. both include GMP) what does Sage do? Are there
two copies of GMP? They could have different versions of the
same package since project 1 could have stopped at one version
and project 2 could have stopped at another. Sage could be
using a third.

  Hi,

  Newer sympy has a bundled copy of mpmath, what causes several
problems in my sagemath package. I was in vacation during most of
Mandriva 2010.1 freeze, and did not fully test the package for some
time, but I am working on an update for it; basically an 's/import
mpmath/import sympy.mpmath as mpmath/', but would like to know what
would be the better approach. (just letting the code use both leads to
SEGvs).

  The new sagemath package will conflict with
python-mpmath-0.14-1mdv2010.1 (forcing it to be uninstalled), because
the sympy is python-sympy-0.6.7-1mdv2010.1.

Hi Paulo,

that will probably be a pain for us in gentoo as well. At the moment we are sticking with sympy-0.6.6 as sympy-0.6.7 gives us trouble. The gentoo philosophy
at this point will be to remove mpmath from sympy and
make it a requirement. But I haven't been actively working
on that.

Francois
