New description:
Numeric evaluation methods for the Nielsen Generalized Polylogarithm are
commented out in the pynac source since it tries to call the `CLN` library
directly. The calls to CLN should be replaced with their MPFR, etc.
equivalents and the function made available symbolically in Sage. The
Pynac part is https://github.com/pynac/pynac/issues/3

Comment:
Ah okay, what was meant in this ticket's description is GiNaC's
implementation of the Nielsen Generalized Polylogarithm which is not in
mpmath. I have changed the description accordingly.
