The following Perl modules are needed for the cluster mode: Event

I would not be surprised that this is related to https://bugs.launchpad.net/ubuntu/+source/dvdrip/+bug/527462

dvdrip has been updated today to version 1:0.98.10-0.2ubuntu7 (that corrects https://bugs.launchpad.net/ubuntu/+source/dvdrip/+bug/527462)
With this version, the behavior is slightly different : when I click on "add to cluster", a window opens (the "cluster control panel"), but with a popup saying that dvdrip-master did not start correctly.

If I start dvdrip-master manually, it fails with the following error message :
$ dvdrip-master

The following Perl modules are needed for the cluster mode:

    Event

Please read the documentation at:

It looks like the Event Perl module dependency has been added to dvdrip package, but is not found by dvdrip-master
I tried to reinstall packages libevent-rpc-perl and libevent-execflow-perl, but it did not change the behavior

As far as I can see this bug seems to be fixed in #527462. But since I am not using Ubuntu 10.04 alpha I can't confirm it. The reporter should verify and then close this bug.

I still can not use the clustering capability of dvdrip.
I checked the behavior in a virtual machine with a newly installed 10.04 alpha 3 : the problem is the same, so it's reproductible.

In fact, I had two different error messages :
- "Compilation failed in require at /usr/share/perl5/Video/DVDRip/GUI/Main.pm line 836. Can't locate Event/RPC.pm in @INC" has disappeared once #527462 fix has been released
- Now, I have another message when dvdrip-master launches : "The following Perl modules are needed for the cluster mode: Event"

Both messages seem related to the "Event" Perl package. That's why I did not create another bug in launchpad.
I think we have two options :
- keep this launchpad bug and rename it to something generic like "Clustering feature does not work because of missing Event Perl package"
- mark this bug as fixed (and/ord as duplicate of #527462) and create another one, with the second error message

Tell me which one is preferred.

This bug was fixed in the package dvdrip - 1:0.98.11-0ubuntu1

I'm sorry but even with version 1:0.98.11-0ubuntu1 , I still have the second error message.
It can easily be reproduced this way :
- install the dvdrip package
- run dvdrip-master in a terminal
It prevents from using the clustering feature.

Should I open another bug?

I opened another bug for the error message of dvdrip-master : https://bugs.launchpad.net/ubuntu/+source/dvdrip/+bug/538475

This bug was fixed in the package dvdrip - 1:0.98.11-0ubuntu2

dvdrip (1:0.98.11-0ubuntu2) lucid; urgency=low

  * Depends on libevent-perl (finally closes LP: #521907).
