incorrect checksum in control file error for postgres 9.1.3 data created in osx-Lion and accessed in osx-snow-leopard

Question

I get the following error when trying to start postgres using the data created in another mac machine. FATAL: incorrect checksum in control file

The postgres version is 9.1.3 and the data initialized in snow leopard does not work in Lion and vice-versa. I do not face this issue for postgres v9.0.1. is there any configuration in postgres 9.1.3 which fixes this issue?

You can't move between systems with different operating systems. The compiled versions may have different alignment etc. Do a dump on the old and a restore on the new.
