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.

Just for the record:
Both errors were not related to iemnet's Makefile being based on an old
version of the template. 

The OS X error is (hopefully) fixed now, because IOhannes removed
'-I"$(PD_INCLUDE)/pd"' from ALL_CFLAGS (which was also not part of the
older template version).

The windows error wasn't related to the Makefile at all.

Anyway, it's good it's based on a current template now.
