Hi Amit,
you can look at the following thread for the error details.
http://sourceforge.net/mailarchive/message.php?msg_id=30145224
If you switch to dump branch things should work fine, however, If you need
the wiktionary branch we were planning to deploy Jona's patch to all
branches anyway so we might speed up th procedure :)
Best,
Dimitris
