* Add hostfile component for the LLM (reads hostfiles, returns array of
node identifiers
NOTES:
- This will require the full autogen / configure / make.
- You now need flex to build Open MPI from Subversion. The versions
available on most Linux boxen and OS X is more than new enough. You
do *not* need flex to build from a nightly or release tarball.
This commit was SVN r1890.
