I really don't recall where this pd came from, but command line says: pe...@arkana:~$ pdextended -version Pd version 0.42-5extended-20100530 compiled 09:02:05 May 30 2010
And yes, I'm on karmic (9.10). >On monday, I will try to run my patch with the 0.42.5 rc4 on an Hardy... we will see if it works or >not... In my mind it doesn't "compile" that the issue would be much Ubuntu-version-dependent, but if you say you could easily run 4 instances of this exact patch in Hardy and cannot no longer in Lucid.. something is going on (as Americans say: something "fishy").
