All you have to do is make sure that the LD_LIBRARY_PATH (or
LTDL_LIBRARY_PATH) contains the relevant directory.  Guile *could*
just append it's internal directory to LD_LIBRARY_PATH (or
LTDL_LIBRARY_PATH) at startup, but the would have to be done in code
that's loaded even if you're just using libguile, and we'd need to
think carefully about interactions with any LTDL_LIBRARY_PATH that may
already be in effect when this code runs.

The other option might be adding an -rpath to guile for the internal
lib dir.

Good question.
