I assume this means it can't find libgnutls.so.26 ?

I've tried installing what I *thought* might be the relevant
package(s) from the respositories the machine offers. But still get
the above. I don't know if this means I haven't found it, or if the
machine requires me to re-build on it to make a version of ffmpeg it
will be happy with. (Although simply copying across the executable was
fine on my other machines.)

I've recently upgraded my last remaining Intel-based 32bit PAE systems
(Intel core-Duo and AMD dual Athlon hardware) to X86-64 operating
systems on the same hardware and have seen the same problem with code
that is using dynamically linked libraries. The fix has been simple:
recompile programs that fail this way in the X86_64 environment.

I think I've installed the 32 bit versions of the OSs in the machines I
have. Plan to go to 64 bit next time.

Some other excutables seem OK. For example I have a USB audio recorder
program I wrote some years ago. This uses the alsa dev libs, but may well
have taken what it needs into the executable. However it works with the new
OS.
