No idea about the version of thrust you have - but I've just upgraded
the cuda test machine to use cuda-4.1 [with builtin thrust] - and the
release cusp-v0.3.1 - and the build went through fine.

And I had earlier [a couple of months ago?] noticed that latest
thrust-dev [or was it cusp-dev] of that time diverged such that
petsc-dev would no longer build - and I had to revert to an earlier
working dev snapshots of these packages.
