g++dg/dg.exp newbie usage problem

[dank at kegel dot com]

After much pain, I have the beginnings of a documented procedure
for running gcc's regression tests remotely in the simplest
of cases (two similar red hat linux boxes on a LAN).
It's at
  http://www.kegel.com/xgcc3/dejagnu.html

But the pain isn't quite over yet.  When I run gcc3.0.1's
tests remotely, I get a few failures.  Since I'm a total newbie
at this stuff, I'm sure it's something obvious.  Running
  runtest --tool g++ -v -v -v -v > log1
  runtest --tool g++ --target dual -v -v -v -v> log2
  diff -au log1 log2
should produce no interesting differences, but I get a bunch
of compile-time errors in the remote case (--target dual) in
g++.dg/dg.exp.
That isn't right, as both cases compile on the same machine.
Can someone have a look at my recipe and see if there's any
obvious flaws?
Thanks!
