Where exactly do you get the rabbitmq binaries? May be it's better to
report a bug with the dependency (erlang-base-hipe | erlang-base should
work)?

Can you show the build log (all messages which are emitted during the build)?
At least I'll see if the HiPE is in fact compiled in.

HiPE in Erlang means High Performance, i.e. the Erlang virtual machine
flavor which can compile native binaries instead of a bytecoded ones.

As far as I know, there shoudn't be any reason to require erlang-base-hipe,
erlang-base should work just fine. Mostly, the dependency line looks like
erlang-base | erlang-base-hipe.

Though if indeed the erlang-base-hipe is necessary, I'll try to enable
it on arm64
(if I'll find an appropriate machine for testing).

Cheers!
