But if it's /usr/local we're talking about (/usr/local/lib, /usr/local/include), then it's a problem because the compiler looks there without you needing to tell it to. We'd love to tell the compiler not to do that, but we don't know how to do so in a way that doesn't have other consequences. It's come up many times before and the best we can offer at this time is don't install software in prefix /usr/local. _______________________________________________ macports-users mailing list macports-users@lists.macosforge.org http://lists.macosforge.org/mailman/listinfo.cgi/macports-users
