I've just discovered the following page:
http://code.google.com/p/ocropus/source/browse/wiki/GettingStartedWithAlpha.wiki

It's pretty old, but seems to answer my questions.
There is apparently an svn repo containing patched/correct versions of
both openfst and lepton at http://ocropus.googlecode.com/svn/external/.

I am going to update the issues pages for issues 143 and 145 with this
info.

Thanks.  I thought I had RT entire FM.
