How did you tested it? Did you preform a clean rebuild of gnuradio?

Note that libgnuradio-runtime.so requires libvolk.so.2.2.1 (not libvolk.so) and 
when VOLK is built with ORC it requires liborc-0.4.so.0 (not liborc-0.4.so) and 
this is how it should be, there is no way around this.

$ ldd libgnuradio-runtime.so | grep orc
        liborc-0.4.so.0 => /lib64/liborc-0.4.so.0 (0x00007f46d4f3a000)

To test whether this issue is fixed you need to try building an OOT module 
without having the liborc-0.4.so (the liborc-0.4-dev package) installed on your 
system.
