Thanx for the feedback here, with relevant details :-)

Are you actually running it on your arm board, or running it on an x86
host and targetting the arm board?

This may well be correct.
http://unstable.buildd.net/buildd/armel_Building.html suggests that
glibc 2.7-0exp6 has indeed not yet built (it is currently building)
In this case you probably just want to install the pre-built
toolchains from emdebian.org:

This is rather odd. I don't know why it is looking for gcc2.95, but
there has never been a 2.95 armel cross-compiler (or compiler for
that matter) so this isn't going to work. why emsetup is defaulting to
2.95 I don't know. Neil?

Yes. emchain tries to build a current toolchain if emsetup doesn't
find one installed.

emchain always tries to use the very latest available packages. In
this case it is trying to use one that is available on some arches,
but not this one, which isn't very helpful. There may be room for
improvement there.
