Now I got it on master branch and Luite reported the same problem on #ghc (log above is actually his). A workaround for this is disabling building of dicumentation in "perf" section of `build.mk`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8276 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
