The output for directories containing libexpat.0.dylib is:

So there are definitely two libexpat.0.dylib versions but I'm kind of reaching the limits of my Unix experience here.

Does this help in conjunction with the error message? FWIW, PHP was compiled as an Apache module before the upgrade so maybe that is the offending libexpat.0.dylib...

Thanks,
