 hugs98 prints an error message when running on Mac OS X 10.2, but there
 are two problems with the implementation:

  1. It uses the "`exit`" command which no longer exists.
  2. It should be wrapped in a "`pre-fetch`" block so that non-installation
 actions, like `port info` and `portindex`, still work.

 These are the problems you currently get:

 {{{
 $ sudo port info +darwin_6
 Hugs is not supported on Jaguar (10.2.x). Sorry.
 Error: Error executing darwin_6: invalid command name "exit"
 Error: Unable to open port: Error evaluating variants
 $
 }}}

 I'll attach a patch to fix this.
