Did you try it under UML, or on a plain i386-based GNU/Linux
system?
I could probably arrange for an SSH-accessible UML/amd64
instance, if necessary. Presumably IPv6-only, so one'd be
expected to either have native IPv6 connectivity, or wishing to
invest a few minutes of his (her) own time to, e. g., install
the miredo package.

I've tried to build it under UML, but to no avail. Apparently,
the Erlang implementation used as part of the build process also
fails to run under UML on amd64. See below for details.
