[Python-modules-team] Bug#541746: mpmath is bundled

[Seo Sanghyeon]

Package: python-sympy
Version: 0.6.4-1
Severity: wishlist

python-sympy bundles mpmath. It should use python-mpmath package instead.

/usr/share/python-support/python-sympy/sympy/mpmath/__init__.py claims
its version is 0.11, but source code does not match with mpmath 0.11
release. It seems to be an intermediate version between 0.11 and 0.12.

For example, sympy.mpmath includes Riemann-Siegel Z-function which does
not exist in mpmath 0.11, while it lacks twin prime constant which is
included in mpmath 0.12.

Also, the rest of sympy imports mpmath from sympy.mpmath. Rather than
fixing all imports, maybe symlink to mpmath should be shipped.
