Yeah, but it's one of those things that feels like it must have been
solved by the others in the space. Once it's installed, the concern
goes away (unless you demand absolute relocatability without
recompilation). I'll take a look at how libkrb/libmagick do their
testing.

If it somehow turns out to be impossible, one option might be to shove
a more detailed ABI identifier into the name. In other words, builds
without ENABLE_SSL/GSS/SSPI or whatever get different names on disk.
That doesn't scale at all, but it's a short-term option that would put
more pressure on a medium-term stable ABI.

Thanks,
