Problem compiling Erlang 13B02 on MacOS

I was getting the following error compiling erlang 13B02 on MacOS Leopard:

Thanks to the Google translation of a page in Japanese on javaeye.com (link) I figured out I had to rebuild wxWidgets (even though version 2.8 already seems installed in Leopard). Here's the nub of it:

• Download wxWidgets 2.8.x, untar to a directory of your choice
• cd into the un-tarred directory and make a build dir (eg. mkdir MYBUILD)
• cd into that new directory and build a static install into a destination of your choice (I put it in /opt/wxWidgets28):
  ../configure --with-opengl --enable-unicode --enable-graphics_ctx --enable-gnomeprint --disable-shared --prefix=/opt/wxWidgets28
  make
  sudo make install
  cd contrib/src/stc
  make
  sudo make install
• Now you can build OTP/Erlang properly, but make sure the new wx-config is first in your path, eg:
  PATH=/opt/wxWidgets28/bin:$PATH ./configure ....
