I think it would be inelegant to stuff pkgsrc with numerous ".if
exists(libc.so.12.83.1) || exists(libc.so.12.90)". "exists()"
doesn't even take shell globs, does it? Better to grep for something
in the system headers.
That reminds me, though: there are other uses for the library version
numbers in pkgsrc. This proposal generated 0 responses, however:
