Yeah, this is deliberate:
http://darcs.net/Development/Policy#ghc-versions - I'm fairly sure that
we've also now made code changes that won't work on GHC 6.12.

5 years is a long time in GHC terms!
I'd suggest downloading a binary distribution of a more recent GHC from
http://www.haskell.org/ghc/download, and use that to build darcs.
To install the binary, unpack it somewhere, ./configure
--prefix=/some/where ; make install
Then point your PATH at /some/where/bin, and build darcs.
