I imagine you can set LD_LIBRARY_PATH or edit where the system finds shared libraries to allow the compiler to find the shared gmp/mpfr (though it is possible it might make other programs that use gmp/mpfr to behave differently if they load up a different version than they were linked against). -- Michael Meissner, IBM 4 Technology Place Drive, MS 2203A, Westford, MA, 01886, USA meissner@xxxxxxxxxxxxxxxxxx
