It's very curious, I can see no reason whatsoever for the audacity on
the 'bad' system to ask for libSoundTouch.so.0, searching for name
using the 'strings' command produces the following:-

    chris$ strings /usr/bin/audacity | grep libSound
    libSoundTouch.so.1
    chris$ 

The two binaries (/usr/bin/audacity) are identical.


I have also compared the system call sequence using ptrace and the two
systems are near enough identical except that the 'bad' one loads
libSoundTouch.so.0.  However there is a difference here, the 'good'
one goes straight to /usr/lib/x86_64-linux-gnu/libSoundTouch.so.1
whereas the 'bad' one searches through the whole series of possible
library locations before finding libSoundTouch.so.0.
