It would be nice if there was just one line in packages/Makefile that  
just ran:

./configure --with-pd=/path/to/pd

As it is now, there has to be a separate target for each platform  
since "./configure" alone doesn't work, and the options to get it  
working are different on each platform.  I.e. Apple needs --without- 
ImageMagick, Debian needs --disable-sse2, etc.  Its ugly and ugliness  
seems to always lead to problems down the line.  It works for now tho.

Also, having the Pd-extended build system just call "./configure"  
without extra options would mean that you could change the default  
build options for the auto-builders without having to touch packages/ 
Makefile.  You would just change the defaults in configure.ac.
