Hi Dave,
The easiest way for this to happen is for June 98 Hugs to try loading
a January 98 Prelude (or t'other way about).
Sadly, the Prelude and libaries don't contain easily identified version
information so, to check, you have to look at file modification dates
or look closely at the output of "make install -n" or check in case
make install is producing some error such as the Hugs executable being
unwritable.
If this is the problem, the fix probably involves a little more care
when running the configure script (being sure to rm config.cache
first, of course).
