Seeing the names on this list I realize I've tried lots and lots of 
different things. I'm running kernel 2.6.15.11 so I'm above 12. 
Unfortunately the latest misdn-mqueue does not compile on my system, it 
issues all sorts of blah-blah that I'm interpreting in only one way: 
there's a problem with the parameters the Makefile passes to the 
compiler (the .h files where the error manifests itself are part of 
Asterisk and compile fine when compiled with Asterisk itself).

Those are the errors I get:

./create_config.sh "/usr/include"
