[dvd::rip] Can't create project

[dark_mail@xxxxxxx]

When trying to create a new project with either version 0.98.6 oder
0.98.2 DVD::Rip raises an error or crashes (with an identical message):

Can't locate auto/Data/Dumper/Sortkeys.al in @INC (@INC contains: lib

"Sortkeys.al" is nowhere to be found on my system (Linux).
Perl is 5.8.8-r2 (Gentoo).

I don't know which part failed, dvdrip itself, perl or transcode.
Maybe you can make something out of it ...
