LGTM.

I don’t have any great ideas.

If it uses lt_dlopen, then we should recommend setting LTDL_LIBRARY_PATH
instead of LD_LIBRARY_PATH, which is a lesser evil.

Otherwise, we could also hard-code the file name of, say,
guile-dbd-sqlite in guile-dbi, such that there’s always at least one
backend available.

WDYT?
