I am a bit fuzzy on this, but I suspect that with regular ld can link a
library which uses another library and have that dependency be pulled in
(ldd shows .so having dependencies other .so files), but that with
dlopen the dependencies have to be there already.

I don't have a good idea for a portable fix, other than extending dlopen
to behave like ld.

What happens on platforms where linking a shlib doesn't get the
dependencies?  Is this something libtool does with .la to pull them in
at link time?  Or am I just confused?
