[NTG-context] Using Mkiv

I have Texlive installed on Ubuntu Linux x64. The version is listed as "2009-11." According to http://wiki.contextgarden.net/Running_Mark_IV#Introduction, with this version, I should be able to compile by typing context filename.tex at the command line, but I get the error MTXrun | forcing cache reload MTXrun | resolvers: warning: no lua configuration files found MTXrun | resolvers MTXrun | resolvers MTXrun | the resolver databases are not present or outdated MTXrun | resolvers: using suffix based filetype 'lua' MTXrun | resolvers: using suffix based filetype 'lua' MTXrun | resolvers: remembering file 'mtx-context.lua' MTXrun | resolvers: using suffix based filetype 'lua' MTXrun | unknown script 'context.lua' or 'mtx-context.lua'
