Erlang *builds* on Unix, true, but it also builds on Windows and
VxWorks.  It's not "written for Unix" specifically.

The AXD 301 runs the "VRTX" operating system, which is described here:

and which AFAICT appears to be called "Nucleus" these days:

which _is_ a RTOS.

I don't think the issue is ignored at all.  Customizing your operating
system is why ports/pkgsrc/etc exists.
