Thanks for your rapid response, Eric.

I tried darcs 1.0.9 (after patching it to work with ghc 6.8.2 using 
instructions I found online).  It succeeded (at least, it printed "Done

same error when I run any command.

Since "darcs get" fails on this repo, I put a tarball of the repository at


(David Roundy might recognize it -- this is descended from a project 
[http://ab-initio.mit.edu/meep] that he started when he was in our group 
at MIT, and he's the reason it uses darcs of course.)
