Hi
Should the error messages should
indicate where stap is trying to resolve the symbol name from ?

The missing package is kernel-debuginfo{-common}-2.6.32-358.6.2.el6.x86_64.
The stap-prep scropt would help you install it.
Or for your specific script, this may be enough:
probe kprobe.function("vfs_read") { printf("read performed\n"); exit() }
