 I'm on OS 10.9.3, GHC 7.6.3.

 Please let me know if I can provide any other info that could be helpful,
 or if a full output would help.

Comment:

 Thank you -- that looks bad.

 You say "Version = 7.8.2" in the ticket header, but then in your comments
 you say GHC 7.6.3.  Let's assume the comments are right.

 I've just successfully done `cabal install yi` with (something very close
 to) 7.8.2.  So I think it's probably already fixed. Do re-open if you
 disagree.

 Simon
