Well, the options are probably the same if you use the same Makefile (or are
perhaps your gentoo compile options different?), but try this:

machine1$ gcc -E file.c >machine1.i
machine2$ gcc -E file.c >machine2.i
machine2$ diff machine1.i machine2.i

You will probably discover that they are not entirely the same, which would be
why you get a cache miss.

One more thing: Are the source files on the same path on the two machines?
I think that is included in the checksum as well.
