OK, perhaps I should be clearer.
Perl versions 5.8.1 through 5.8.8 were considered 'binary-compatible' by
p5p. Most XS modules built against 5.8.1 will work correctly with 5.8.8
without rebuilding. This is not true of mod_perl: since it uses
undocumented calls, it requires rebuilding for *any* change in perl
version, even one advertised by p5p as 'binary-compatible'.
Perl version 5.10 is considered by p5p to break binary compatibility.
All XS modules, mod_perl included, will need to be rebuilt. Perl
versions 5.10.x will, almost certainly, be binary-compatible with
5.10.0, so again modules *other* than mod_perl won't need to be rebuilt.
In my original reply I confused the '5.10 is binary-incompatible with
5.8' and the 'mod_perl is never binary-compatible under any change in
perl version' parts of the above.

Thank you for your charity :), but I wasn't and didn't. The
clarification is appreciated.
