The goal here is to use the GNUstep runtime (and libdispatch) for
Objective-C code. The runtime needs to include the interface required
for using blocks with Objective-C (for example, it needs to properly
retain or copy Objective-C objects referenced in the block while copying
blocks to the heap).
When you are using libdispatch from the package, it links against
libBlocksRuntime as the blocks runtime interface, which knows nothing
about the GNUstep runtime and doesn't do quite the right things. So
using the package doesn't get you anywhere in this scenario, hence the
minor annoyances described earlier.

Cheers,

Niels
