Hey man, thank you for getting back to me on New Years Eve !
Now that is dedication right there :-)

Yeah, it is not exactly easy hardware to have laying around. I suspect
something funny is at work here in my Fujitsu SPARC world. I was going
to rebuild readline again and give it a whirl. Tomorrow maybe. Or

If you want access to a build box just drop me a line with a public key.
I still have these great hulking Oracle Fujitsu boxes running and I
suspect I will for years. Some people really don't want to migrate code
and that goes double when it is piles of Fortran IV stuff ported out of
older IBM Mainframes.
