I don't know about the tcltk errors, but for the rest...

Note: when setting CFLAGS and CXXFLAGS, it overrides the default  
optimization in configure, so you should add optimization to these.  I  
suggest -Os for OSX, or that default which is -O2.

see below for missing LDFLAGS note...

render.c should compile now, though nviz_cmd won't work.  No need to  
delete render.c.

When compiling as a universal binary (ppc + i386) you must also set  
LDFLAGS.  The libraries need that for linking.  Only source compile  
and program linking use C/CXX-FLAGS.

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly  
what the universe is for and why it is here, it will instantly  
disappear and be replaced by something even more bizarrely  
inexplicable.  There is another theory which states that this has  
already happened.
