Hi Russell,

It should be possible to use the latest LTTV with the trace reading
library v2.3. To do so, keep the one you already installed, then

- Compile and 'make install' 0.12.35 on top of it.
- Change the symlink in /usr/local/lib/liblttvtraceread.so to point to
_2.3 instead of _2.6


Granted, if the bug you're hitting is in the library itself this won't
help, but you might have more success if it's not.


Cheers,
Alexandre
