How to use with current BAP, e.g. v2.2 or higher?

[tnballo]

Following the setup instructions, running opam install bap-server and building from source (after figuring out LLVM dependencies, etc):

• It seems bap-server uses ~/.opam/system/bin/bap. This binary is version 1.4.0, quite old.
• Installing the latest release .deb packages on the system doesn't change the version used by bap-server, I think.

How can I configure the Python bindings to use a current BAP version through bap-server? Maybe bap-server can be added to the Debian releases, since it's a bit challenging to build?
