configure expects m_pd.h to be in the default search paths.
this should probably be handled by the "-with-pd" flag to configure (but
it is not).

it might work if you set the INCLUDES when running configure:

%> INCLUDES="-I/Users/cefn/Documents/curiosity/pdplay/pd-intel/"
./configure ...

(this is one line!)

this should save you from the following:

what is the output of configure?
how do Make.config and Base/configDarwin.h look like? (that is: after
configure)

is there any mention of "mmx" somewhere?

it seems to be a problem with MMX.

however, looking at the code again, it might be that there is a problem
with variable name "nil" (as defined in line277 of pix_chroma_key.cpp)
you could try to replace all occurences of "nil" with "null64".
probably that's all. (if so, you might have to change it in a couple of
other files too)

if you still get the same errors, then there IS an issue with MMX.
you might try to add "-U__MMX__" to the gcc-flags.
or add a a "#undef __MMX__" somewhere at the beginning of Base/GemSIMD.h
(line 30 seems to be fine)
