The newest library template version handles this much better.  I think its something that IOhannes worked out with the PD_INCLUDE var pointing directly to the dir that actually has the headers, and PD_PATH pointing to the root of the Pd tree.  The default include statement is now -I$(PD_INCLUDE) so its easily overrideable.
