If your compilation (or your importing within python of a .so library)
fails complaining of an "undefined symbol", use
nm to locate it within the relevant libraries. For instance,
nm -o /usr/lib/*.so* | grep Undefined <symbol>
then add the library (those listed with "T" define the symbol, and do not just use it) to the linking step in your makefile.
This one was a killer to find.
