Looks like not being up to pick up uninstalled libraries.  You may
like to use strace (or similar) to investigate where the system is
looking, and see if there's a way to tell it to look in libguile.  (We
try to do this with the LTDL_LIBRARY_PATH variable, but perhaps that
isn't working on HP-UX?)

OK, so there's a factor of 3 there.  Can you try changing the hardcode
stack limit in eval.c from 20000 to 60000, and see if that allows the
affected tests to pass?  If it does, we'll have to find a way of
applying the factor in libguile/stack-limit-calibration.scm before
Guile starts booting.

OK, thanks.
