The default should be based on what is found when mpl is built, so it 
sounds like when you are building v1.2.x, none of the supported gui 
toolkits is being found.  I don't know why that is.  Are you installing 
on a system that has gui toolkits already installed?  One useful 
technique with ubuntu derivatives is to do

sudo apt-get build-dep python-matplotlib

It might pull in more than you really want, but it will certainly 
include gui toolkits.
