All, I am using Mactex Texlive 2008 on a Macbook pro. I did this: sudo ctxtools --updatecontext After reading http://wiki.contextgarden.net/Running_Mark_IV, I tried: sudo rsync -av rsync://contextgarden.net/minimals/current/context/ current/ /usr/local/texlive/2008/texmf-dist/ sudo rsync -av rsync://contextgarden.net/minimals/current/bin/luatex/ osx-universal/bin/luatex /usr/local/texlive/2008/bin/ Then I try: david-arnolds-macbook-pro:~ darnold$ sudo luatools --generate And I get: sudo: luatools: command not found Then I tried: david-arnolds-macbook-pro:~ darnold$ luatools --generate The result was: -bash: /usr/texbin/luatools: Permission denied Trying the context command yields the same result: david-arnolds-macbook-pro:~ darnold$ context --make Result: -bash: /usr/texbin/context: Permission denied So, there is some sort of permissions problem. We looked at this: david-arnolds-macbook-pro:texbin darnold$ cd /usr/texbin david-arnolds-macbook-pro:texbin darnold$ ls -l lua* lrwxr-xr-x 1 root wheel 6 May 13 17:46 lualatex -> luatex -rwxr-xr-x 1 root wheel 8009384 Aug 13 2008 luatex lrwxr-xr-x 1 root wheel 49 May 13 17:46 luatools -> ../../ texmf-dist/scripts/context/lua/luatools.lua And tried: david-arnolds-macbook-pro:texbin darnold$ ls -l ../../texmf-dist/ scripts/context/lua/luatools.lua -rw-r--r-- 1 33 33 222585 Aug 14 01:50 ../../texmf-dist/scripts/ context/lua/luatools.lua And see that this file is not executable, so we try: david-arnolds-macbook-pro:texbin darnold$ sudo chmod +x ../../texmf- dist/scripts/context/lua/luatools.lua Now the following works. david-arnolds-macbook-pro:texbin darnold$ luatools --generate But this piecemeal approach to making things executable might go on and on. Can someone give a more universal cure? Is there an entire directory of scripts that need to be executable? Thanks. David
