I emphatically agree. I think Darin did some preliminary work back porting fixes to 7.6, but life's gotten busy so he couldn't finish it https://github.com/darinmorrison/ghc

Hi all,

It's getting more urgent to have a working GHC on OS X Mavericks. 35% [1] of OS X users are now on Mavericks and won't have a working GHC unless they jump through some hoops [2]. If we don't think we can have 7.8 out in the next few days, I think we should consider making a minimal 7.6.x release to make things work on OS X again.
