[Discuss-gnuradio] Missing uhd_swig

I updated my Fedora version release 28

Afterwards I had to rebuild GNU radio (of course) to get GNU radio companion to even load.

I though my work was done, but now that I've tried to use GRC, I am getting the following error when I go to "Execute":

Any help appreciated.

Thanks
