Nico Schmidt submitted a patch that will get incorporated into the current
source to fix this problem. It turns out that contrary to the MIPSPro C++
compiler, the GNU C++ compiler (g++) does not mangle names differently
depending on which ABI you're targeting (o32,n32,n64).
The whole point here is that we need to know what the mangled name for the
initClass() method will be. This way after dlopen() has been called on the
shared lib we can invoke the method which initializes this class.

The bigger problem with the fonts is that we are using a library called
libFL which we cannot re-distribute at this point in time. Hopefully
someone will replace the font library with libfreetype.

Hope this answers some of your questions ...
