A few days ago I put some work into the hope.cabal file, so that you  
should now be able to use that to build it. Just get the versions of  
all packages listed in the current darcs version of hope.cabal. I  
think all of them except the haskelldb ones are available from  
Hackage. If haskelldb 0.10 was released and uploaded to Hackage, I  
think you could even install Hope itself from Hackage.

I've also recently changed the version number scheme on most of the  
packages I maintain (which includes most of the packages required by  
Hope) from a date-based one to a major.minor scheme. This has the  
unfortunate side-effect of making newer versions have smaller version  
numbers than older ones, but it felt silly to start with a major  
version number of 2008. That might have been a bad decision.
