I would try linking against the static libraries, and see whether you 
get errors in that case. (Thinking that link time errors might be easier 
to decode than runtime link errors.) On the Mac, this is probably 
easiest if you uniquely name the static libs and change your -l params 
to the linker. If the dylib and the static lib are both in the linker 
search paths and their names only differ by extension, then the linker 
will prefer the dylib, so the rename is the easiest workaround for 
testing. (Or maybe change the dylib names to something that won't get 
found and leave the linker commands alone. That's a smaller perturbation.)
