For using modules, the version specified is, by default, the minumum version. The same is true of perl itself, so:

use 5.010;
use Text::Diff 1.40;

[download]

means that the script must be run using perl 5.10 or newer and must be able to load Text::Diff version 1.40 or newer.

See the docs for use for more detail.
