 Hi,

 currently port select gcc only changes the binaries in $PREFIX/bin.

 However, at least some ports use /usr/bin/cc as the default compiler.
 This ports will likely end up using whatever /usr/bin/cc is set to - for
 instance llvm-gcc42 if XCode 4 was installed, although the user MAY have
 selected gcc42 manually and lives under the impression it's used.

 Then again, I don't know, whether it's a good thing to fiddle outside of
 $PREFIX, so I'll open this for discussion.

 I'd vote for yes and moreover possibly also change all other symlinks in
 /usr/bin as gcc, g++, c++ etc. BUT symlink them to their /opt/local/bin
 counterparts, so we don't need to keep two places in sync.

 Best regards,


 Mihai
