You should create a symlink to libcsound64.so.6.0 in usr/lib:
cd /usr/lib
sudo ln -s libcsound64.so.6.0 libcsound64.so

It's a cleaner way.

Then the Attribute error is due to the fact that the csoundCompileTreeAsync method didn't exist in Csound6.09.01. You should use the ctcsound.py file shipped within the apt package instead. The ctcsound.py file in the github repo is synced with the develop branch of Csound and thus it can refer to methods that don't exist in earlier versions of Csound.

I found libcsound64.so.6.0 in usr/lib. I changed the ctcsound.py - file to:

if sys.platform.startswith('linux'):
    libcsound = CDLL("libcsound64.so.6.0")

Unfortunately I get an error:

import ctcsound

AttributeError: /usr/lib/libcsound64.so.6.0: undefined symbol: csoundCompileTreeAsync
