 Thank you for testing that. Could you attach the new main.log so I can
 compare it with mine?

 would be causing an issue when macports' prefix is /opt/local.

 It is nevertheless the case. Many projects hardcode /usr/local as a place
 to look for things; although we try to patch these out when we find them,
 we are unlikely to ever find all such occurrences. More importantly,
 /usr/local is a special directory: the compiler looks for things in it,
 even if we don't tell it to; we don't know of a way to tell the compiler
 not to do that, so the only thing we can do is tell people not to install
 things there.
