taco and i are clueless ... we need more info
I think there is a problem with input.aux.expanded_path ... I have more or less the same system as Oliver, and this week-end I had the same problem as him, but with today's release I have a different one: (I changed only the PATH) # luatools --generate LuaTools | variable SELFAUTOLOC set to /Users/arthur/TeX/ConTeXt/tex/texmf-osx-intel/bin LuaTools | variable SELFAUTODIR set to /Users/arthur/TeX/ConTeXt/tex/texmf-osx-intel LuaTools | variable SELFAUTOPARENT set to /Users/arthur/TeX/ConTeXt/tex LuaTools | variable TEXMFCNF set to {$SELFAUTODIR,$SELFAUTOPARENT}{,{/share,}/texmf{-local,.local,}/web2c} LuaTools | no cnf files found (TEXMFCNF may not be set/known) LuaTools | LuaTools | runtime: 0.028 seconds Apparently the problem is to be traced back to input.aux.expanded_path, because it expands {$SELFAUTODIR,$SELFAUTOPARENT}{,{/share,}/texmf{-local,.local,}/web2c} into $SELFAUTODIR/share $SELFAUTODIR/texmf-local/web2c $SELFAUTODIR/texmf.local/web2c $SELFAUTOPARENT/share $SELFAUTOPARENT/texmf-local/web2c $SELFAUTOPARENT/texmf.local/web2c which is not correct, because it should also expand to .../texmf/... (see the trailing comma in {-local,.local,}). Arthur
