It sounds like we need an alpha implementation (and mips?) of our
assembly code...
I don't think anyone in the community currently supports either of
these platforms, unfortunately.

I'm sorry, I was supposed to let you know about this, as this openmpi
failure is keeping arpack++ out of Lenny. The real problem is that
openmpi is FTBFS on alpha, see below.
Can anybody dive in there and sort this out?
The openmpi buildd log on alpha [1] ends with:

warning: implicit declaration of function 'opal_sys_timer_get_cycles'
Okay, found it. This function is inline assembly in timer.h, which
exists in opal/sys/amd64, ia32, ia64, powerpc and sparcv9 but not
alpha,
mips, sparc or win32. That said, timer.h in opal/sys has:
#ifndef OPAL_HAVE_SYS_TIMER_GET_CYCLES
#define OPAL_HAVE_SYS_TIMER_GET_CYCLES 0
which somehow is working on sparc (no reference to this function in
the
buildd log) but not alpha. (On mips, there are a bunch of assembler
errors of the form "opcode not supported on this processor".)
That's about what I have time for now. Don't worry about mpi-
defaults,
it's not trying to get into Lenny; but we should worry about OpenMPI
not
building on alpha. Does anyone on us...@open-mpi.org have any ideas?
