Building Boost.Python on FreeBSD4.9 with gcc 3.2.3

I'd like to build Boost.Python on FreeBSD4.9. Initially doing a pkg_add 
for boost revealed that the python library (libboost_python) does not 
come with the package. So I decided to build form sources. I've set my 
PYTHON_ROOT and PYTHON_VERSION variables like this:

essendon# setenv PYTHON_VERSION 2.3
essendon# setenv PYTHON_ROOT /usr/local

I've upgraded my compiler from 2.95 by installing gcc3.2.3 using pkg_add:

pkg_add -v -p /usr gcc-3.2.3.tgz

This places executables gcc32 and g++32 into /usr/bin.

I've built bjam from sources like this:

./build.sh

Next I change directory to /usr/tmp/boost-1.30.2 where I've extracted 
the boost code and run bjam.

essendon# ../boost-jam-3.1.10/bin.freebsd/bjam "-sTOOLS=gcc" 
"-sGCC=gcc32" "-sGXX=g++32"

This doesn't work as expected and produces the following output:

...found 3380 targets...
...updating 496 targets...

"libs/python/build/../src/numeric.cpp"

Basically where it says "g++ -c -Wall -ftemplate-depth-100... " I expect 
it to be using g++32 as dictated by -sGXX=g++32. In this case the g++ 
refered to is version 2.95.4 which comes with FreeBSD 4.9 release.

So I follow the work around here 
http://www.mail-archive.com/[e-mail]/msg11162.html and 
comment the lines mentioned.

Then trying the same command:
essendon# ../boost-jam-3.1.10/bin.freebsd/bjam "-sTOOLS=gcc" 
"-sGCC=gcc32" "-sGXX=g++32"

gives the following output:

etc....................

For what it's worth I don't have any problems on Linux (Gentoo) building 
Boost.Python from sources or using the version of Boost that you can 
emerge from portage.
