thanks for the info.
it is possible that somehow during my install my connection was reset.
that might explain the missing objects.
it is very strange that iemlib was one of the few uninstalled libraries , most of the pd-...libs were allready installed by default with the fresh install of ubuntu studio, i have that drive disconnected currently but will uninstall and reinstall to check. I looked in the ext/iemlib folder and did not see the missing patches.
pd-0-46.0 is working great by the way with ALSA and with Jack on AMD and INTEL 64 bit machines.
