Ah, Windows. I meant to ask you to test cabal-install on Windows at  
the hackathon, but I didn't get that far. I think that it is looking  
for /etc/cabal-install, which you probably don't have. I should set  
up GHC in my Windows VM and get it working. You could try --config- 
dir=<some Windows dir where you have put etc-cabal-install/serv.list>  
in the meantime. You need to run cabal-install update as the first  
thing you do too.
