This is a fairly new CD install of Precise (yesterday, in fact) followed
by "aptitude update" and "aptitude safe-upgrade" from a local
Ubuntu mirror, then manual installation of my favourite packages.

I removed libgmp3c2 to get back to Square One.

Description: PARI/GP Computer Algebra System binaries
 PARI/GP is a widely used computer algebra system designed for fast
 computations in number theory (factorizations, algebraic number theory,
 elliptic curves...), but also contains a large number of other useful
 functions to compute with mathematical entities such as matrices,
 polynomials, power series, algebraic numbers etc., and a lot of
 transcendental functions. PARI is also available as a C library to allow
 for faster computations.
 Originally developed by Henri Cohen and his co-workers (University Bordeaux I,
 France), PARI is now under the GPL and maintained by Karim Belabas
 with the help of many volunteer contributors.
 This package contains the GP calculator.
