The VXML code requires the header files for the expat XML parser to be installed on your system. If you are using Unix, then make sure you have the “expat-devel” package installed. If you are using Windows, then a recompiled version of expat and the required header files can be downloaded from http://www.voxgratia.org/bin/expat_lib.zip.
