NEW: ntl

[ralf@…]

This port is a C++ library implementing (amongst other things) polynomial and bignum arithmetic. It provides efficient algorithms for lattice reduction, polynomial factorization and for basic linear algebra. Unfortunately Apple's gcc 4.0 gives up with an internal error when compiling it, thus we use gcc 3.3 on the Darwin 8/MacOS X 10.4 platform.

thanks, commited with changes: -replaced build.env-append with build.args-append -changed g++-3.3 etc. to full path -added missing homepage key -made dep on gmp in gmp lib definitiv
