If you pull from xcvb,
I have a trivial patch to remove grain-sets from the build.
It's quite possible I packaged the xcvb tarball
before I pushed fare-quasiquote to the public git — my mistake,
and pulling should fix it indeed.

please use SBCL or CCL, or else CLISP if neither is available on your platform.

Thanks. This is fixed in asdf 2.26.4.

Fixed in xcvb HEAD.

Ooops, there was a spurious backquote in dependencies-interpreter.lisp.
Fixed in xcvb HEAD.

Still, when I get past it, I find that XCVB ends up
trying to load a .so the wrong way.
The CFFI and/or dynamic library support has bitrotten
(if it ever worked on ECL).
I see that compiling CFFI now fails on SBCL, too,
and at least requires re-merging a newer CFFI for xcvb.

I will investigate.

That's weird. I will investigate.

I'm sorry XCVB is not ready for you yet :-(
I will get back to you...
