Hal,

Linux distributions normally provide a libc-libstdc++ compatibility package
that provides the appropriate stubs & symlinks for older versions of the
libraries - you should be able to search the packages for your distribution
for the relevant filename in order to locate the package.

Regards,

Wez @ RealVNC Ltd.
