I have indicated earlier that I would have liked to import openmp into base, but this was shot down precisely for that reason: nothing in base uses it. So for now, the solution is simply: install one of the llvm ports, and use it. These have configuration setting to install every optional component from the LLVM project. -Dimitry --Apple-Mail=_3536ECCC-D717-4A86-896F-0178616DC4A0 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.30 iEYEARECAAYFAlfC31IACgkQsF6jCi4glqMIhgCfQdTyf1iUdQ2+9uRKdFeJ/Gra VDUAoIVsZ6BWpgSTd/REr+1AB3JnJb1q =AKfx -----END PGP SIGNATURE----- --Apple-Mail=_3536ECCC-D717-4A86-896F-0178616DC4A0--
