Ehm, nearly. There was an error in setting the compiler. Please use
the files attached below.

You should be able to typeset the current document synchronously with

  :make

or asynchronously with:

  :ConTeXt

This latter command also accepts an optional path, in case you want
to typeset a document different from the current buffer.

In either case, 'mtxrun' must be in your $PATH. If necessary, you may
set the path explicitly with

  let g:context_mtxrun = '/path/to/mtxrun'

Something like

  let g:context_mtxrun = 
'$PATH=$HOME/context-beta/tex/texmf-osx-64/bin:$PATH mtxrun'

should also work.

Finally, you may check the status of the background jobs with

  :ConTeXtJobStatus

and possibly kill all running jobs with

  :ConTeXtStopJobs
