You don't need the haskell-platform to build the docs; I suspect you're
missing dblatex.

You'd need to look at how the tests failed. If you add
    TEST="T5430 parsing001 spec-inline"
to the command you were running the testsuite with then it'll run just
those tests, which will make it easier to see what's happening.

I'm not familiar with the HP build script, I'm afraid.
