Probably this patch will help with Crypto:

<http://anonscm.debian.org/cgi-bin/darcsweb.cgi?r=pkg-haskell/haskell-crypto;a=filediff;h=20120213034652-b2814-0019a3f92e453e9be86166d6c1f1bc0dad6e4d12.gz;f=patches/class-constraints.diff>

Or, there's the `ghc7.0` branch of git-annex in git, which can be used to build with the older, stable ghc.

BTW, when asking, for help, a log of the build failure is always a good idea..
