Yes, I synced my working copy of ghc 6.5 yesterday with darcs pull.
Are there any requirements as to which exact version of ghc 6.4 I am 
supposed to use?
I am using the plain 6.4 release but I am able to build the head of the 
6.4 branch.

BTW. Am I supposed to run configure after syncing the working copy 
and/or clean the source tree before issueing the make command?
