vsViewer reveals problem with vapoursynth.so (I think)

[drfear]

Oh I can't believe I be so dumb.  Of course.  I've been having a lot of trouble with setting $ LD_LIBRARY_PATH="/home/vsimon/opt/vapoursynth/lib" globally - it breaks tons of things, notably mpv (oddly, because as far as I can see, the libavcodec in vapoursynth and /usr/lib are the same).  So I had added /usr/lib:..., partially masking vapoursynth.

So yes that's a great help, thanks, at least now I get the environment set ok.  However I still have a problem - no lsmas component:

$ LD_LIBRARY_PATH="/home/vsimon/opt/vapoursynth/lib" python

... so I can't load any clips .-(

Actually give me an hour before taking any time to respond.  It occurs to me I might have had /usr/lib first in my path when I compiled ... I'll try a recompile

well no, it wasn't that.  I had re-run config.txt so I did everything by the book. I have
