Current releases of Octave do not require anything from libg++.

It is certainly possible to install multiple versions of egcs or gcc
on the same system.  I usually do it by specifying completely separate
installation prefixes.  I use --prefix=/usr/local/gnu/gcc/VERSION, in
which VERSION is replaced by the actual version number.

Sorry, but it's impossible for me to tell exactly what the trouble is
with your system.
