Did you change the version of SWIG you were using? Configuring --
with-swig reruns SWIG which recreates the generated wrapper code.
Unfortunately, even a minor change in SWIG version number can lead to
dramatically different wrapper code. To get the Ptr classes back,
start with a fresh copy of libSBML 2.3.4 and omit the --with-swig
configure option or make sure you're using SWIG 1.3.24.
