~/Library/Preferences should only be used if the .plist format is
supported. In general, I agree with Brendan that unixy programs don't
belong here, and I'm happy with .cabal. However, if you want to use
the OSX dirs, I would think that most of the items in .cabal could be
placed in ~/Library/Application Support/Cabal/. Unlike most other
standard directories, this appears to be completely

All preferences are in ~/Library/Preferences/, in Apple's .plist
format. There is no ~/Applications/Preferences/.
Build logs should go in ~/Library/Logs/, either in a subdirectory or
directly in this folder.
There is a ~/Library/Caches/, but I believe that's reserved for the
NSURL cache (accessed through Cocoa).

I have personally ended up just copying the latest version of
"appname-n.n.n" to "appname". Granted I've only done that on my own
computer, never as part of an install process.
