I have released hledger 0.6.1 which fixes a build problem with ghc 6.8. You can ignore this release if you use a newer ghc or if one of the http://hledger.org/binaries works for you. Thanks to Andreas Reuleaux for the report. More reports welcome on irc, list or http://code.google.com/p/hledger/issues . Best, -Simon (sm)
