Problems with hat

[Boey Maun Suang]

Hi Max,

If this bug with the hat port hasn't been fixed for you, could you file
a ticket on Trac for it?  (See
http://guide.macports.org/#project.tickets for how to do so.)  I'm
afraid that I can't help you directly, but at least this way it's
properly listed.  Also, if anyone is a Haskell-on-MacPorts guru, some
love this way would be appreciated!

Kind regards,


Maun Suang
