William is correct.  HPPA support is not gone from Guile; and indeed
it's good to hear from you :)  I wasn't sure there were any IA64 users

Initially in Guile I planned to use GNU Lightning, in part because of
its great platform support.  However it turned out to not be the right
thing, and reluctantly I ended up doing something that was more like a
rewrite than a refactor.  In that context I personally don't have the
budget to write the IA64 backend.  So, Guile 3 still runs on IA64, just
without JIT support.

If someone would like to write an IA64 backend for Lightening, I would
be happy to accept it :)  The beginnings of one are there in the git
