ruby33 fails on Tiger: error: 'MD5_Init' undeclared here (not in a function); did you mean 'CC_MD5_Init'?

Also, looks like pthread part should have a fallback for 10.4, though it does not err out on this code:

In file included from thread.c:263:0:

I fixed this ages ago, but never saw the ticket. It should be closed.
