The issue isn't with dlopen().

It's with MSP_locate_file() in mal_linker.c.

MSP_locate_file() throws a runtime error if open() fails,
and the call to open() assumes a .so with no version
suffix.  This logic assumes a certain setting of the
libtool variable library_names_spec, which can vary by

In fact, there's already an #ifdef _AIX in that function that
ignores the open() error, so this has come up before for
another platform.
