Unable to build XV

[Richard L. Hamilton]

I’ve not only seen that across various macOS versions, but something else broke the existing xv because one of the ports the older version depended on changed where it keeps some libraries. Specifically, the older version of xv expects

/opt/local/lib/libjasper.4.dylib

but the new location for that seems to be

/opt/local/libexec/jasper2/lib/libjasper.4.dylib

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.
