unknown required load command 0x80000022

We're using the MySQL++ library for a project. I've built it on Snow Leopard targeting MacOS 10.4 as the minimum version, but whenever I try to use it on Leopard (10.5), I get the following error when trying to load libmysqlpp.3.0.9.dylib:

dyld: Library not loaded: @executable_path/../Frameworks/libmysqlpp. 3.0.9.dylib
Referenced from: /Volumes/Extras/Users/cruisecontrol/.hudson/jobs/ OSX-10.5-Licenser-CI-Debug/workspace/trunk/Licenser/build/scons/ scons-out/dbg/staging/./AdminServer
Reason: no suitable image found. Did find:
/Volumes/Extras/Users/cruisecontrol/.hudson/jobs/OSX-10.5-Licenser- CI-Debug/workspace/trunk/Licenser/build/scons/scons-out/dbg/ staging/./../Frameworks/libmysqlpp.3.0.9.dylib: unknown required load command 0x80000022

Trace/BPT trap

It's being built with gcc/g++ 4.0 and with the following environment variables set prior to running the ./configure script:

export CC="gcc-4.0"
export CXX="g++-4.0"
export CFLAGS="-arch i386 -arch ppc -mmacosx-version-min=10.4 - DMAC_OS_X_VERSION_MIN_REQUIRED=1040 -isysroot /Developer/SDKs/ MacOSX10.4u.sdk"
export LDFLAGS="-arch i386 -arch ppc"

I'm also changing the install_name after build to @executable_path/../ Frameworks/libname after it's built.

Any ideas on why I'm getting the above error on Leopard when built from Snow Leopard targeting 10.4?

Thanks in advance.
