Dear all,
LibXtract 0.2.2 is now available on sourceforge http://sourceforge.net/projects/libxtract it includes a PD external that provides an interface to the functionality of the library.
0.2.2 Fixes a few problems with the build system, namely that it didn't work on OS X.
It would be great if those who responded first time round could try it again on their OS X systems.
best,
Jamie
