[Boost-build] Building boost in 32 bit mode on Linux 64

I'm attempting to build a 32 bit BOOST library on 64 bit CENTOS.  Using g++ 
version 3.4.6 20060404 red Hat 3.4.6-8

I finally figured out how to generate and compile the cod as 32 bit but I've 
run into a couple of problems.

My environment is set as:
export PATH=`pwd`/tools/jam/src/bin.linux:$PATH
export CFLAGS=-m32
export CXXFLAGS=-m32
export LDFLAGS=-m32

32 bit libs are being generated in build 
subdirectories ./bin.v2/libs/date_time/build/gcc-3.4.6/debug/address-model-
32/architecture-x86/threading-multi/libboost_date_time-gcc34-mt-d-
1_34_1.so.1.34.1

But those libraries aren't being copied into a single directory at the end.  
Am I missing something?

Also, I noticed a compiler error which effected some of the compiles.  The 
error was: "LONG_BIT definition appears wrong for platform (bad gcc/glibc 
config?)." from /usr/include/python2.3/pyport.h.  I have confirmed that I am 
using a 64 bit version of Python.

Thanks for your help.
