Haskell's ecosystem is far from all "wine and roses": my few experiences with cabal were not what I hoped to put it mildly, since 2010 I have a yearly yak shaving ritual called "try to install leksah" that only this year was successful, and last time I've tried to install the latest version of the Haskell platform on my Ubuntu box, had to build it form the source manually installing the profiling packages on one by one.
In no way it qualifies as "miles ahead of Scala"
