GHC HEAD broken on OS X

After doing a 'git pull origin master && ./sync-all pull origin master', I get the following build failure when stage1 attempts to compile the RTS code: http://paste.debian.net/121097/ A quick glance at the errors seem to indicate this work is related to the new events stuff for GHC. Duncan was working on this last I think - is anybody else experiencing this failure? -- Regards, Austin
