This is a bug report for perl from Ulrich.Windl@rz,uni-regensburg.de,
generated with the help of perlbug 1.35 running under perl v5.8.8.

Message "... version 6.2 required--this is only version 6.10..."
It's not well-described in "man perlfunc" how versions are actually compared.
When using RCS-like software to update the version number, expectations are
that RCS' ascending version numbers would be treated numerically as well in
Perl. It seems, they aren't. I ran into a problem after making a change from
version 6.9 to 6.10 (see above).
Reading the documenatatio nafterwards did not help much how perl actually compares numbers.
Regards
Ulrich Windl
