[OSX] milter won't build

[rdack]

trying to build milter module 0.3.9 on OSX 10.1.2 i get this error:
cc -bundle -undefined suppress build/temp.darwin-5.2-Power
Macintosh-2.1/miltermodule.o -lmilter -lsm -o
build/lib.darwin-5.2-Power Macintosh-2.1/milter.so
/usr/bin/ld: -undefined error must be used when -twolevel_namespace is
in effect
error: command 'cc' failed with exit status 1

is it telling me i need  an '-undefined error' option? or that it
doesn't like the 'undefined suppress' option?
where is the 'cc -bundle' command set up? can i edit it?
is it possible that it finished and the module is ready to go? 
where would the milter module end up after install?
what will its name be?
are python modules '.pyo' files? do they end up in the
/usr/local/lib/python2.1 directory?
help?
