 I think the same problem arise for binaries (htdig, htsearch ...) which
are installed in prefix/bin without version number appended anywhere. I assume
every system administrator is aware of that pitfall since it's the same
with most packages. What we could provide is a GCC like installation scheme:
you never destroy an existing installation and can switch back to a previously
installed by changing a few symbolic links. I've never done that myself but
it seems possible.
 I'm afraid such a scheme would be overkill for most people. On my system
I would rather install a new htdig version in a separate directory
($HOME/local) and try it before replacing the system version in /usr/local.
It's also a bit more complex to do since there is no direct support for that
in automake.
 Let me know if this seems particularly important to you.

 Cheers,
