Oracle InstallationCompat-GCC is required. I encountered the following problems in rhel5.4:
[Root @ localhost RPM] # rpm-IVH compat-gcc-34-g77-3.4.6-4.i386.rpmwarning: compat-gcc-34-g77-3.4.6-4.i386.rpm: Header V3 DSA Signature: nokey, key ID 37017186 error: Failed dependencies: compat-libf2c-34 = 3.4.6-4 is needed by compat-gcc-34-g77-3.4.6-4.i386 libg2c. so.0 is needed by compat-gcc-34-g77-3.4.6-4.i386
This is because the dependency pack compat-libf2c-34-3.4.6-4.i386.rpm is installed.
