Re: libg++ header file locations...

Your process is flawed and will always fail (unless you get lucky).  A
process that works better that I have used for 5 years is if you
configure with --prefix=/abs/name/package_name-package-version; make;
make install.

You can then symlink all the */bin directory elements into a main bin
somewhere.

For example on my system I have:

$ ls ~/packages/
Acrobat3        binutils-2.8.1  dejagnu-970918  egcs-ss-970814  rcs-5.7
autoconf-2.12   cvs-1.9         egcs-970825     emacs-19.34     tor-1.0.1
automake-1.2    dejagnu-970707  egcs-970907     emacs-20.2      trn-3.6
bash-2.01       dejagnu-970907  egcs-970924     less-332

and in the bin 
$ ls ~/bin
total 4269

As you can see, I have 4 versions of the compiler, and they always
just work, they never don't work.  I can never find leftovers from
previous installs, and so on.  All useful properties.
