LinuxQuestions.org - C++ preprocessor "/lib/cpp" fails sanity check

Hi,

I know there are already similar posts to this but (as far as I can tell!) I might need a slightly different resolution...

On trying to configure libogg

C++ preprocessor "/lib/cpp" fails sanity check

Config.log reads:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.59. Invocation command line was

$ ./configure

From what i've read im guessing that my GCC doesnt have the right C++ components. I've tried to install gcc-c++-4.0.2-8.fc4.x86_64.rpm and get this error:

error: Failed dependencies:
libc.so.6()(64bit) is needed by gcc-c++-4.0.2-8.fc4.x86_64
libc.so.6(GLIBC_2.2.5)(64bit) is needed by gcc-c++-4.0.2-8.fc4.x86_64
libc.so.6(GLIBC_2.3)(64bit) is needed by gcc-c++-4.0.2-8.fc4.x86_64
libstdc++-devel = 4.0.2-8.fc4 is needed by gcc-c++-4.0.2-8.fc4.x86_64

I then tried glibc-common-2.3.5-10.i386.rpm (on the basis that it showed up when I searched) it turned up:

warning: glibc-common-2.3.5-10.i386.rpm: Header V3 DSA signature: NOKEY, key ID 4f2a6fd2
error: Failed dependencies:
glibc > 2.3.5 conflicts with glibc-common-2.3.5-10.i386

All of the rpms have been listed as appropriate my my system (fedora c4) - I'm new to all this stuff so think i'm stabbing in the dark - any suggestions would be greatly appreciated!

If this helps at all gcc -v:
