By installing the c++-compiler you specify in your call to
configure?

 One thing which suprizes me is that while the configure
command
is in error passing a wrong c++ compiler name on the command
line
argument, I don't understand why it affects libxml2 as we
don't
need a C++ compiler anywhere, just a C one. There may be
something
to fix there,

Without having checked detail, this looks like a side effect
of this
freaking bug in libtool, which pulls in checks for all
languages libtool
supports into configure scripts.

This bug renders many packages using libtool almost
unbuildable on many
platforms which don't have a working c++-compiler installed
(Many
embedded toolchains).

this bug will be fixed in Libtool 2.0.

It might helpto use CVS version of libtool, but I'm not
sore what are
the prerequisities for that.
