[Discuss-gnuradio] "Could not find port: cfg in:" error

[Jason Matusiak]

This is the same problem I had once before, but I am not sure why I 
can't fix it this time.  I have an RFNoC OOT module that wants to have a 
msg port input.  I called this port 'cfg'.

Attached is my freqShift_impl.cc file where I declare the message port 
"cfg".  I also included multiaperture_freqShift.xml where the port gets 
declared as a sink.

When I make and make install, everything seems to run fine.  I do a sudo 
ldconfig, and then refresh GRC.  When I build it is happy, then when I 
run I get the following error:

Could not find port: cfg in:
rfnoc

The last time I had this issue with a block it was because I didn't make 
the changes to my .cpp and .h files, but I did that this time. What else 
could I be missing???
