I had no problems compiling from /Downloads/pd-045xxxxx/src then looking for all the symbolic links and launchers that point to the default installed 'puredata' package that comes with ubuntustudio 12.10 except that I installed some of the guiplugins and now pd will not close from menu or window x button. I have looked and looked for that script that sets that and can not find it. running 'pd' from terminal and ctrl-c works to close. I'm getting a stack overflow on loading of xensynth in pd-extended , actually a couple of them but it still works. I did notice the other day that I'm still getting crackles when I play the version with the string emulator. I'm thinking it's something to do with wish and the mouse, about has to be because it happened in windows when I last checked october 2012, the same crackles. the common denominator would about have to be wish + mouse.
