Comment:

 I have a question about its implementation, currently it is opening the
 Portfile to find out the homepage. Wouldn't it be sufficient to rely on
 the value in the PortIndex and only open the Portfile if the value is not
 available there? This would make the command run faster.

 Attached is a patch for `port/port.tcl` to implement this behavior. It
 also fixes the errors if no homepage is available as reported originally.
