avl.rs:10:1: 10:17 error: found possibly newer version of crate openssl which db depends on
avl.rs:10 extern crate db; a system with 2 different version openssl

Can you explain the issue a bit more, this is pretty cryptic as-is and it's difficult to understand the question here.

with different version of one share library , how could them compile together , for example rust-postgres
depends on openssl-#123, rust-http depends on openeel-#456, there exists a project need both rust-postgres and rust-http, how can i do to compile them together to one execute program.

The rust compiler supports multiple versions of the same library through symbol mangling, and cargo supports the same as well. It sounds like there's not much of a bug here, so I'm going to close this.
