 Attached is a darcs patch to bootstrap.sh. I should darcs send, but can't
 right now.

 I added -c to wget. This prevents wget from downloading an archive again
 and naming it whatever.1, whatever.2, etc. curl redownloads, but
 overwrites the original.

 I think I improved some messages.

 Instead of saying "if all went well, cabal should be in ...", I check
 whether cabal exists where it should be.
