Some changes in dependency ranges. After a bunch of tests, now haskintex is more likely to build at the first try. However, you will need GHC 7.8 at least. This is a pretty important restriction right now, but a new Haskell Platform should be released soon with GHC 7.8.2, making easy to have the last version of haskintex in all platforms. In the long term, this restriction will become meaningless.
