 Essentially, there are a bunch of places in the build system where we
 forget to quote paths, and so the spaces collapse into a single space and
 the paths fail.  I fixed a few low hanging instances of this but I got
 hsc2hs to fail:

 }}}

 Notice that there is only a single space in the `include` path passed to
 hsc2hs. I didn't feel like tracking down where we didn't quote enough.
