gmr1_rach_scan

Hi, I try to use the gmr1_rach_scan flowgraph, but did not succeed. I am always getting this error: Traceback (most recent call last): File "/home/peter/Radio/Thuraya/sylvain-gr/osmo-gmr/gr-gmr1/apps/gmr1_rach_scan.py", line 22, in <module> from gnuradio import gmr1 ImportError: cannot import name gmr1 Anyone can help me how to compile and install correctly the needed blocks for the flowgraph? Thank you.
