You cannot evade the terms of the GPL by shipping components
separately when you would not be allowed to ship them together, nor
does it matter whether two different people do the shipping.

Remember always that the GPL applies to the whole program, not to
individual files, functions, or lines of code.

If the GPL'd source is only useful with GPL-incompatible libfoo, then
you and the shipper of libfoo are combining to ship a program which
contains incompatible licenses, and this is not allowed.

If the GPL'd source is useful with various equivalent libraries, some
GPL-incompatible, some not, then the shipper of the GPL'd source is
not breaking any rules, because they are not necessarily intending to
combine their code with the incompatible code.

If you are shipping *binaries* however, which declare shared library
dependencies on the GPL-incompatible library, then that excuse
