Hey Roberto,
I just tried to install libstdc++-devel-3.2-7.i386.rpm, but RH told me that it was already installed...
I then tried to configure it without cxx and openssl and it configured fine, but as I wanted to gmake it, it died with tons of errors...
What did you have to modify to make it work with 7.2.3? Although I would rather be able to install 7.1.3! Any more hints?
