I have been following the whole thread, and obviously the sytem issued 
this  "unknown command" message because it didn't find or recognize an 
executable file in its path, but *nobody explained how it is possible.*

You confirmed vuescan  /(this file features an 'application' icon)/ was 
in /home/john/VueScan and "$ /home/john/VueScan/vuescan" is the proper syntax 
to call it.
On later mail you also confirmed it has the "x"

Alvin's suggestion was interresting:
"on a side note: Your /home partition isn't mounted with 'noexec', is it?" 
You didn't answer this explicitely but I guess it was, right?
*Could someone confirm  "unknown command" is what the system answers in such 

Then you moved Vuescan to /opt and ldd spoke about missing files, which 
implies ldd considered this vuescan as an exe, and got into it.
From this I conclude that if you had tried $ /opt/Vuescan/vuescan the message 
was no longer "unknown command".

Strangely Ed Hamrick, the author of the application, failed to recognize your 
initial problem of "unknown command" but correctly pointed to your second 
problem, the missing library.

Does it work now?
