Comment (by Dave-Allured):

 Erik, it looks like you did not use **"-v"** in your `port install`
 command.  If this is correct, then would you please clean the port, then
 run the install command again with `port -v install`, then post the new
 main.log here?  This will give me some more complete debug info.  Thank
 you.
