Hi Tom,
Did you, after you install your OOT module, run the following in your
terminal?:
sudo ldconfig
Cheers,

Sorry, me again.
Recently did a fresh install of ubuntu 16.10 and did a apt install
of gnuradio.
A few days ago you helped me get my OOT blocks properly installed
on my own tree by added square brackets around my <category> value.
However there are now problems when I run:
File "/home/tom/grc-flow/top_block.py", line 147, in __init__
self.ambe3000_dstar_encode_sb_0 =
ambe3000.dstar_encode_sb('/dev/ttyUSB0', 230400)
AttributeError: 'module' object has no attribute 'dstar_encode_sb'
I'm having trouble finding useful info googling on this error
message. I have spend several days following various threads,
including rebuilding another, identical OOT from scratch with
gr_modtool.
My OOT is at https://github.com/ac2ie/gr-ambe3000
<https://github.com/ac2ie/gr-ambe3000> . (This OOT worked fine
with ubuntu 16.04.)
Here is top_block.py:
