When I first read this, I was worried that I had a chicken/egg problem, but I found that you can do with the host's version of those libraries. I found a port of gnu libmpfr, but I notice here that FreeBSD has it's own libmp, and I don't know if the 4.3.1 version of gnu gcc can use our libmp, or if I need to install the port "libgmp4" and tell the gnu gcc configure about which mp I'm using. So, if you know if I can use FreeBSD's libmp, or if I need to build the ports libgmp4, please let me know. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkndT6YACgkQz62J6PPcoOmsiQCff6qjZ46dxn8P+5c19gAP2dip 3YsAnj2/sy3nhZzk1TWz1Rfv7PQ2Uw5f =5iqj -----END PGP SIGNATURE-----
