I just googled the text of the license for the blocks runtime (i.e.
libclosure), and it looks like it's the MIT license... can't MIT-licensed
packages be used in GPLed projects? After accounting for the ambiguity of the
name, the GNU license list seems to say they're compatible:

https://www.gnu.org/licenses/license-list.html#X11License
or
https://www.gnu.org/licenses/license-list.html#Expat

The libclosure license can be found at the top of:
http://opensource.apple.com/source/libclosure/libclosure-65/BlockImplementation.txt
or
http://opensource.apple.com/source/libclosure/libclosure-65/BlockSpec.rtf
(if anyone wants to verify)
