So there are definitely issues between xv and jasper2.

I worked around the existing broken xv binary using a symlink for the library (which if it all gets fixed, I’ll remove by hand as I created it by hand). But other than that, I have no particular familiarity with the innards of either xv or jasper2, although many years ago I compiled xv for Solaris.
