If either apt-get or port worked that’s fine.

You installed GNU Radio without performance counters. This block is only for 
profiling, so no problem. I will remove it from the flow graphs.

I guess you installed the module with a different CMAKE_INSTALL_PREFIX and 
thus, the blocks ended up in a different directory and GRC can’t find them. I 
added this to the Readme, please see
 
https://github.com/bastibl/gr-ieee802-11/commit/cee6ec82a8356db8fad7496c2617a5d3fac4b0e5

You did not install the hierarchical block as Kartik wrote.

If the some ports are still unconnected after all blocks are found please check 
the mailing list. This came up several times. You just need to reconnect them 
in GRC (don’t forget to check the hierarchical block too).

Don’t panic :-)
