I understand that.

The initial message was crossposted to debian-sparc@lists.debian.org too.

I can't build it on UltraSPARC III because I don't have an access to
it. The binaries that are built on UltraSPARC II don't work on
UltraSPARC III (It can be concluded from FTBFS of erlang-based
packages (e.g. ejabberd which FTBFS too currently).
I guess you might start building erlang on UltraSPARC III and after
virtual machine is built (executables beam*) you could simply replace
existing binaries from erlang-base (version 11.b.5-8) and try it on
UltraSPARC II. But I'm afraid it's too complicated.
