Hi all, I tried to update my installation using svn version of luatex and context from: http://mirror.contextgarden.net/context/beta/cont-tmf.zip Running "texexec --make --all --luatex" gives me this error message: LuaTools | running command: luatex --ini --lua="cont-en.luc" "/opt/context/tex/texmf-local/tex/context/base/cont-en.tex" \\dump (/opt/context/tex/texmf-local/tex/context/base/cont-en.tex (/opt/context/tex/texmf-local/tex/context/base/context.tex (/opt/context/tex/texmf-local/tex/context/base/syst-pln.tex) (/opt/context/tex/texmf-local/tex/context/base/syst-prm.tex) (/opt/context/tex/texmf-local/tex/context/base/luat-env.tex !

Could you give me a hint? Thanks ZS
