Okay. I've modified to configure script to fix the extra space issue, and to
push LDFLAGS and CFLAGS onto the environment before cabal attempts the build. It
should also correctly handle the --extra-[lib,include]-dirs flags now. Hopefully
that goes smoother in future...

I had a look though the makefiles used by the NVIDIA examples on my ubuntu test
machine, but found no mention of searching /usr/lib/nvidia-current, so I'm not
sure where that came from. Maybe that's part of the examples installer script,
but I'll have to look into that later.

That is a good point. Some of the tests are expected to fail but that's not
written down anywhere yet; I'll add a README.

The stack overflow errors come from the reference implementations, not the
accelerate code; give the RTS more space to play in with "+RTS -K32M" or
similar. Off the top of my head permute-hist, radixsort, one of the slice tests,
and scanseg-sum fail.


Thanks for the bug reports so far!
