Lazy binding was introduced with 6.5.0, it is not available for 6.4. But
even in 6.5.0 you would need to use dlopen on your first library to take
advantage of RTLD_LAZY. Then after dlopening first library you could
dlopen product specific library. Nice thing about this is that you would
not need to do dlsym on symbols from product specific so. Alas, this is
all not available in 6.4.x

With 6.4.x you would have to use dlsym on your product specific library
to get to its symbols.

If you provide more detail on what you want to do, maybe we could help.

For example:
* can you determine product before running your app?
* can you determine product in your executable, without dlopening
universal or product specific shared libs?
