6.12.1 Mac OS X installer lacks all HTML documentation
After upgrading GHC from 6.10.4 to 6.12.1 using the installer package for Mac OS X Leopard, I found that the local HTML documentation (aside from moving from
/usr/share/doc/ghc/html/index.html) was lacking a few parts. Specifically, the links to the user's guide, GHC API, and Cabal no longer lead to extant documents, and I was unable to find the documents that they should link to anywhere in the
/Library/Frameworks/GHC.framework/Versions directory. The only local link that still works is the link to the library documentation, and its index page still lists some modules that are no longer distributed with the current version of GHC (specifically, the mtl package, though there may be others that I haven't come across).
This was observed on Mac OS X 10.5.8 with gcc 4.0.1, though it may or may not also apply to other systems.
