Hi, Camm --

Dave Greve reported a 2.6.1 bug (Linux) yesterday that is a bit of a
show-stopper for certain uses of ACL2:

   '(ftype (function
                 ((satisfies integerp))

  results in the error:

  Error: (satisfies integerp) is not of type STRING.

I'd be happy to re-send his email if you like.

   Not a bad idea.  Binary or source?  What do other binary package
   providers think?

   OK, I think we need to finalize 2.6.1, and all build the *same* tree
   and place on the website.  We might call this 2.6.2 if people like,
   and then proceed to work on 2.7.0 pending critical bugs that may
   appear.  Anyone have 'showstoppers' that need fixing in 2.6.1?  Seems
   to work great for me with itself, maxima, acl2 and axiom.

   Take care,
