bug#40952: gnuradio-osmosdr: no hook into gnuradio block directory?

[Christopher Howard]

Hi, I installed gnuradio and gnuradio-osmosdr, but when I open
gnuradio, none of the osmosdr blocks are available from gnuradio blocks
list. Specifically, I was looking for osmosdr source block, which I am
familiar with from using gnuradio under Debian. I believe the problem
is that the osmosdr blocks are not in the directory where gnuradio-
companion is looking for blocks.

When starting up gnuradio-companion, stdout indicates grc is looking for blocks 
here:

/gnu/store/h2igg2gcbx6ds8wbvlkqz0dkplvwjxbd-gnuradio-3.8.0.0/share/gnuradio/grc/blocks

But osmosdr blocks are in 

/gnu/store/ppb504vizb32f4w2s5f0yd6i4xpy41nz-gnuradio-osmosdr-0.2.0/share/gnuradio/grc/blocks/

Evidentally gnuradio package needs to be enhanced to create a per-
profile merged directory from all gnuradio- block packages that are
installed. Unless there is some way to extend the gnuradio search path
through environment variables.
