so i've been having a problem with MT for a while, where it wouldn't rebuild the index page when a comment was added, and thus the comment counts would never get updated correctly. i never was able to figure out why, and i know other people who have had the same problem...
well, to make a long story short, i finally got motivated and looked around the MT message boards and found this thread. it turns out that it's a bug in the code that determines if the index has actually changed, and it only happens if you don't have Digest::MD5 installed.
