This one you probably don't want to apply, but I'm sending it to point
out a much larger problem.  Programs that muck with library paths really
need to figure out what the rules are on the local system and deal
appropriately.  On NetBSD one needs -Wl,-R (or just -R really) to point
to the libdir at runtime when linking, not just -L to find the library.
This is not an issue on linux because of the common use of /usr, I think.

There are more serious issues with dynlinking of .so modules, and on
Darwin there are some PRs open about guile and guile-using programs that
I don't yet fully understand.

I think the fix involves a configure test to decide the -R rules, and
then conditional code to behave differently.
