Comment (by punkish):

 I downloaded the latest MacPort pkg again, reinstalled it, and ran `sudo
 port -v selfupdate` and got the following message


 {{{

 So, what does "Warning: All compilers are either blacklisted or
 unavailable; defaulting to first fallback option" mean and what do I have
 to do to correct this?
