libmpc2 0.9-4build1 (armhf binary) in ubuntu quantal

 MPC is a portable library written in C for arbitrary precision
 arithmetic on complex numbers providing correct rounding. For the time
 being, it contains all arithmetic operations over complex numbers, the
 exponential and the logarithm functions, the trigonometric and
 hyperbolic functions.
 .
 Ultimately, it should implement a multiprecision equivalent of the ISO
 C99 standard.
 .
 It builds upon the GNU MP and the MPFR libraries.
