The issue here is that `g++ 2.96' was never a released compiler. See
http://gcc.gnu.org/gcc-2.96.html
That did not stop some Linux distros distributing a compiler claiming to
have that version number, but with serious bugs. This was all a very long
time ago (2000!), and gcc 3.4.4 is good. (There are some issues with
gcc 4.0.0, some of which are resolved in 4.0.1 released last week.)
It would make sense to install an updated compiler suite and rebuild
R using it: since this is likely to a Linux OS (you did not say) it would
be prudent to update the whole OS since many many bugs and security holes
are known in Linuxen of that vintage.
