My installation of 5.2.4 on my old trusty RedHat 7.2 server failed with the error message:

./boinc: /lib/i686/libc.so.6: version `GCC_3.0' not found (required by ./boinc)

I spent some time trying to find a more current version of GCC for my sytem, but quickly ran into dependency issues.

Anyone have a suggestion (short of rebuilding the system)? It's a production server for in house work.

You will need the gcc libs (libgcc and libstdc++) Version 3.x.
Can you please post the output of "ldd ./boinc_client".

I had a good guess about that. I have GCC version 2.96

You have got to download and install the gcc 3.x libs...
