ah yes, sorry, did see that, just didn't register when I was trying this

ok tried this, but now getting (from trying to compile cxc/counter):

ld -bundle -bundle_loader /usr/local/pd/bin/pd -flat_namespace -o
cxc.pd_darwin *.o -lc -lm
ld: Undefined symbols:
dyld_stub_binding_helper
saveFP
make: *** [darwin] Error 1

Which is just (on the topic of usability) making me nuts. I am now so
&^%@£ed off that I'm just pining for Debian. But, this is a departmental
computer, and making PD work on OSX is something I said I'd do, precisely
because a lot of MAX/MSP users here would like to/might try PD instead...

But I'm just not getting very far with this. Will try again later if I
feel less depressed  ;)

Ah yes, quite. But of course, when you get a makefile like
rhythm_estimator's (which to the ignorant eye looks hugely more
complicated than, say, chaos's, which already has multiple targets), I
just don't even know where to begin separating the bits and declaring
additional targets...

Is there -any- chance that people who made 'cxc' and 'rhythm_estimator'
might take a look at their makefiles to make them more osx friendly (yup,
I realise people have lives)?

Meantime, any comment on error above would help, and be appreciated...

In general, should I just trash makefiles in there (for whatever external
does not have a darwin target) and just slink a darwin target in myself?
Because it seems to me that there is -large- differences in makefile
styles across the externals...which makes it rather confusing.

Is it possible that we (you, the actual developers) might agree on
guidelines for external makefiles, so little bugs like me can better
study/learn the practice and start to understand?
