I cannot build darcs with cabal on either of my two windows machines (one 32
bit running Windows XP, the other 64 bit running Windows 7)

Both of them are using the 2010.1.1 haskell platform for windows (and thus
GHC v 6.12.1).

I send this here with the belief that the darcs team is responsible for
hashed-storage, or that you'll be able to forward it to those who are.

Sincery, Barend Venter,

Command line output follows:

I also get this on my Windows 7 64-bit machine, Haskell Platform 2010.1.1.

Thanks for the report(s)!  We should have this addressed by Darcs 2.4.2.
Could you both confirm that hashed-storage 0.4.12 builds for you?

The darcs hashed-storage dependency is (deliberately) pinned to one
precise version of hashed-storage (for predictability).  We'll have a
patch shortly to modify the darcs.cabal file (but please feel invited to
try this out yourselves and report back)

hashed-storage 0.4.12 also does not build for me.

Whoops, mistaken identity about the problem, sorry Craig and Barend. 
Petr, I believe this one is an easy one for you to fix?  Thanks!

Fixed in h-s 0.4.13.

Confirmed, hashed-storage 0.4.13 now builds for me.  Thank you!
