64 bit linking error

[Gideon Simpson]

I'm trying to compile something using the macports openmpi (built on macports gcc48), and am getting the following linking error:

openmpicxx -I/Users/gideon/software/sprng4.4/include -o sprng_mpi sprng_mpi.cpp  -L/Users/gideon/software/sprng4.4/lib -lsprng  -I/opt/local/include/openmpi -L/opt/local/lib -lmpi_cxx -lmpi
Undefined symbols for architecture x86_64:
 "std::ctype<char>::_M_widen_init() const", referenced from:
     mult_48_32(int*, int*, int*) in libsprng.a(libsprng_a-lcg.o)
     operator<<(std::ostream&, BigNum const&) in libsprng.a(libsprng_a-bignum.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [sprng_mpi] Error 1

This is using a library called SPRNG (http://www.sprng.org), which I built on the macports gcc 48.

Going through the listserv archives, there was something about this over 2 yeas ago, but it was unclear to me how/if it was resolved.
