CVS2Git is generating blank dump file

Question

CVS2Git is generating blank dump file everytime I run the command:

 ./cvs2git --blobfile=git-blob.dat --dumpfile=git-dump.dat --username=NL475475-v --fallback-encoding='utf8' /cygdrive/d/NewIDM --sort="xsort.pl"

OR

./cvs2git --options=test.options --fallback-encoding utf-8 --sort="xsort.pl"

Somehow no error is displaying. The output shows:

 ----- pass 1 (CollectRevsPass) -----

There was some problem with the custom perl sort function. I've also tried GNU sort from http://unxutils.sourceforge.net/ . But it was not working. Now it works using latest updates (after 14-04-03): UnxUpdates.zip at same page.
