If you figure out how to make it work, please post the method

+Dealing with the 64-Bit Transition in Snow Leopard
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ By default, the command-line compiler that comes with Xcode for Snow
+ Leopard wants to build 64-bit binaries, even if your system is booted
+ into 32-bit mode. This can cause various problems, such as a
+ failure in the "configure" step when it's trying to find the MySQL
+ C API library, if it was built as a 32-bit library only.
+
+ There are many ways to skin this cat. Here are the ones I prefer:
+
+ First, you can force the default compiler to build 32-bit binaries:
+
+ ./configure CFLAGS=-m32 CXXFLAGS=-m32 --other-flags-here
+
+ Second, instead of using the GCC 4.2 compilers which default to
+ 64-bit, you can configure the build system to use the GCC 4.0
+ compilers instead, which default to 32-bit:
+
+ ./configure CC=gcc-4.0 CXX=g++-4.0 --other-flags-here
+
+ Last, you could just take Apple's implied advice and start booting
+ your Mac into 64-bit mode, if it will support it. Here's an article
+ that goes into all the details:
