The news is both good and bad when trying to run Hat on OS X 10.5...
The bad:
• The ghcsym bug appears to have returned.
The good:
• Readline is there by default, so nice stuff happens in hat-observe,
and the make file glitch doesn't bite.
• Other than the ghcsym bug, the compile went through smoothly first
time, that's a new one for OS X!
