Fail to build

[benjamin-bergia]

I want to give a try to prx, it seems very interesting. Unfortunately I run into the following error during the build:

[..]/deps/alcove/c_src/sys/clone.c:21:9: note: #pragma message: Support for namespaces using clone(2) enabled

I am running Fedora 28 and OTP-21.0-rc1. I am using erlang.mk to manage my project.
Am i missing any dependency or anything?

Maybe this will work:

ERL_LIBS="" rebar3 do clean, compile

There's a bug in the rebar config of the alcove dependency. If a version of alcove is in the erl search path, rebar skips running some config checks.
