libstdc++.so.5 and RHEL5 64 bits

During the installation process PP complains about libstdc++.so.5 missing.

trying to install the library with yum will install the latest version libstdc++.so.6

Solution: Install compat-libstdc++ library. This is an older library provided for compatibility reasons such as this. It can co-exist with libstdc++.so.6.

Note: There are two versions of compat-libstdc++ in the Red Hat Network (RHN) repository. compat-libstdc++-33 and compat-libstdc++-296

To install:

sudo or become root
yum update (to bring your system up to date with RHN.)
yum search compat-libstdc (this should list the two current versions of the compatible libraries)
yum install compat-libstdc++-33 (this will install the GCC version)
