OK, I've installed the #= code at ut, as the 'too many #=' issue was
legitimately standing in the way of the Debian acl2 6.1 package.

I don't know if this will solve this problem or not, but I will look
into this small example on a newly built acl2-gcl locally.  It may be
that I should expect a hang here as this is not acl2(h), right?  Do you
have a binary setup at ut for me to look at?  In general, are the acl2
variants now deemed 'no longer experimental' and if so should they be
included in the Debian acl2 package?

Will reply separately to the other issues.

Take care,
