I believe this means that if we have a package named "hs-save-the-whales" that is under the GPL, and a front-end package "hs-redeem-them-for-valuable-cash-prizes" which makes use of the functionality in hs-save-the-whales, the front-end MUST be offered under the GPL, and, additionally, CANNOT be offered under BSD (I think).
If you incorporate GPL code into a binary you want to distribute you have to comply with the GPL. Static linking a GPL library will incorporate GPL code into your binary, ergo you have to comply with the GPL. If you write a client of a GPL library and you want to distribute it, your client can be any GPL compatible license - it does not have to be GPL. Should you distribute a compiled binary you have to comply with the GPL and any additional terms brought in by your GPL-compatible license. Its that simple - until there is a court ruling to decide otherwise.
