Comment(by jkeeler@…):

 I had no luck with the CFLAGS option, but --without-framework-carbon
 option above worked for me. Using OS X 10.7.1

 I also had success with this patch file, with carbon framework enabled.

 Also had to add this line to the Portfile:
 {{{
 patchfiles patch-src-display.cc.diff
 }}}

 and place the diff file above into
 /opt/local/var/macports/sources/rsync.macports.org/release/ports/math
 /octave-devel/files folder
