hdevtoolsrelies heavily on theGHCAPI, which goes through major changes with each new release ofGHC.Currently
hdevtoolsis tested withGHCversions:7.6,7.4, and7.2A quick look at the docs for
GHC 7.0.4shows that it is missing several functions thathdevtoolsuses (such asprintException, which is listed in one of your build errors).Making
hdevtoolscompatible withGHC 7.0is something that I currently have no immediate plans for, but patches would be welcome (provided that they don't mutilate the source ofhdevtoolstoo much).I suggest that you install the current version of the Haskell Platform (
2012.4.0.0) which comes withGHC 7.4.2.
