I'd expect that on Leopard.  Unless someone does a Leopard-specific build,
I suspect you're out of luck.

Apple adds new stuff to its dynamic loader in every OS release, and the
result usually isn't compatible with earlier releases by default, in my
experience (that'd be from Tiger through Lion at this point).  You need to
specify an ABI compatibility level to build stuff that will run on older
releases, including just being understood by dyld.

Part of the problem here is that a default Xcode 4.x install only includes
the 10.6 and 10.7 SDKs.  I'm not seeing any way to customize the install,
so it looks like Xcode 4 cannot be used to build for Leopard; someone will
have to do the Leopard-compatible build on Leopard or on Snow Leopard with
Xcode 3.6.
