Thank you everyone for the feedback.
Marek, yes I'll have to take a look at the linux32 support you have submitted.
Won't there be issues with those .a files working on arm instead of x86?
Should we create a linux32arm folder as well, or can we remove all dependancies
on static libraries?
Matt, I'll look into the existing ticket when I get a chance and will
definitely issue a pull request once I get it working.
Since Subutai said that the Grouper code was not being used, I went in and
stubbed out all of the methods to see if the compile would get any further.
However, the build still failed with the following error:

So the linker is not happy with something and it seems like it might be a
compiler bug. The Raspbian distro ships with gcc 4.6, so I upgraded to 4.7 and
the build completed. However, none of the test scripts exist in the
nta/eng/bin directory. I get the following output from the nupic/run_tests.sh
script:

I can include the full build output log if anyone is interested.
