Unfortunately that does not seem to help, and I suspect this is because the tarball contains aclocal.m4, which does not contain the test_mpich3() marco. I don't know much about autotools, but when I try to delete aclocal.m4 and regenerate it with aclocal I run into a different problem:

Hi Eike,
quick solution:
clone into dune-common, change to the 2.2 branch, apply the patch there and do a 'make dist'.
That gives you a tarball with the patch.
ideal solution: we do that for you, and do a 2.2.2 release of dune-common.

PS: That Archer thing has how many processors?  What's your goal with UG?

Cheers,
Oliver [waiting for new bugreports :-) ]
