...fixed, but I'm still getting some x11 stuff because I have
imagemagick via fink...unfortunately, --without-imagemagick doesn't
seem to work, but --without-ImageMagick does: is it possible to make
this work both ways?

...apparently here I made a typo! I meant to say that m_pd.h IS NOT
being found, even with "--includedir=/absolute/path/to/pd/src": how
else can I set this (outside of PATH environment variables)?

...haven't gotten this far, but it is good to have the "--with-pd=/
path/to/pd/bin" that you added...

...that's the thing: why have two "-Ox" flags if only the last one
is effective? As far as -Os goes, apparently size increasing
optimizations aren't necessarily desirable on a ppc: apple docs
always suggest using -Os...otoh, I've never done profiling of -Os vs.
-O3 code to see if there's any real difference in our case, so it's
just speculation...

...thanx for doing the janitorial cleanup!
