Jouni, I think you're right. If I run LaTeX from the command line I get the error message: warning: Could not open char translation file `cp8bit.tcx'. This is e-TeX, Version 3.141592-2.1 (Web2C 7.5.2) kpathsea: Running mktexfmt latex.efmt fmtutil: unknown format type: latex.efmt. I can't find the format file `latex.efmt'!
But if I run it from TeXShop it runs perfectly: This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009) \write18 enabled. entering extended mode and---- ~ Harry$ which latex /usr/local/bin/latex I don't know whether this is the right forum, but could you tell me how to fix this? I'm running OS X 10.6.4.
