Ugghh.... It looks like scipy wasn't quite what I was looking for. All
I really need is a way of evaluating generalised legendre functions of
the first and second kind. I've actually found a package in sympy that
does this

http://docs.sympy.org/dev/modules/mpmath/functions/orthogonal.html#mpmath.legenq

But this doesn't seem to work in the current version of sage

sage: import sympy.mpmath
sage:
sage: sympy.mpmath.legendre(1,0.5)
mpf('0.5')
sage: sympy.mpmath.legenq(1,0.5)
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call
last)

~/<ipython console> in <module>()

AttributeError: 'module' object has no attribute 'legenq'

Is it possible to install an updated version of sympy that Sage can
use?
