So if a package cannot be built by ghc (for whatever reason, e.g. missing C library dependency), then it cannot be documented either. This is a good deal less than useful. A documentation generator ought to do a reasonable job, even if the code it is looking at is technically not-compilable.
It is because it uses GHC to type check the modules and generate the
signatures. I agree that there should be some kind of fall back but it
would be a great deal less useful of an output.

Was Haddock ever stand alone? AFAIK it used to be part of GHC and then
David Waern separated it into a separate package. I honestly can't think
of how it would ever have been stand-alone (that is not relying on GHC
to do part of the work).
