My system no longer had a /lib64/libgcc_s.so.1 which made it quite unhappy. I eventually copied one over from a fedora live iso i had and things are operational again. Is there some way i can confirm if it was the gcc upgrade?
This looks damning; # gcc-config 2 * Switching native-compiler to x86_64-pc-linux-gnu-4.7.3 ... /usr/bin/python2.7: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory ewarn: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory ewarn: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory
