Are these errors caused by GHC, or should we try to do something about
them? If so, can you please open a ticket on the bug tracker?

Thanks. One small problem:

   $ darcs apply 2010-11-01_GHC7_signatures.patch

   darcs failed:  Patch bundle failed hash!
   This probably means that the patch has been corrupted by a mailer.
   The most likely culprit is CRLF newlines.

Yes, but I don't plan to do this. You could patch your local Makefile.

I have nine versions of GHC installed, and can easily choose which one
to use to build Agda:

   make CABAL_OPTIONS="--with-compiler=<path to ghc>" install
