Hello there, Looks like there is some problem with one of the recent changes to The User's Guide source code as it cannot be built any more [1] (since about June 4). Here is the error message, hopefully it helps with fixing the cause: [..] Build users_guide.ps latex failed users_guide.tex:15584: Cannot determine size of graphic in docs/users_guide//prof_scc.png (no BoundingBox). users_guide.tex:15584: leading text: ...width=645pt,height=428pt]{prof_scc.png} Unexpected error occured [ -f docs/users_guide/users_guide.ps ] docs/users_guide/ghc.mk:26: recipe for target 'docs/users_guide/users_guide.ps' failed gmake[1]: *** [docs/users_guide/users_guide.ps] Error 1 Makefile:102: recipe for target 'all' failed gmake: *** [all] Error 2 Thanks, Gábor [1] http://haskell.inf.elte.hu/builders/freebsd-amd64-head/652/10.html
