If the plan is to port to C (which I am still aboard with(waiting on paper work still though)) 
then it is probably not worth the time to upgrade from 2to3.

I think that most "main stream" distros of GNU/Linux for example Debian, Fedora, and Ubuntu still have 
python pointing to python2 by default. So maybe we should just put in a step in the README or INSTALL
for checking the version of python that the python symlink is pointing to and then have the user change 
it to python2. Or is there a way that we can do this with the GNU autotools? Or I suppose that the script 
could automatically but then we might break other applications that _are_ using python3.

For instance I figured out that issue with the symbolic links when I was 
trying to use Decibel media player (which uses Python2) and my Gentoo install
had Python3 as the default. In that case I just changed the shell script that 
calls the Python app to have it call the direct python2.7 instead of the 
python symbolic link.

I briefly looked over the Gnutrition code that starts the app but there
did not appear to be a way to specify this other then to change the 
#!/bin/python to #!/bin/python2.7 .
