You need to rebuild your so rule files.  Pulled Pork can do this for you.

Thanks to everyone for the responses. I compiled Snort from source (I had originally installed using Ubuntu apt-get), configuring it with --enable-large-pcap. I downloaded rule set 2930 and set it up, configured the snort.conf file, and when I try to run it now, I get:

ERROR: The dynamic detection library "/usr/local/snort/lib/snort_dynamicrules/imap.so" version 1.0 compiled with dynamic engine library version 1.16 isn't compatible with the current dynamic engine library "/usr/local/snort/lib/snort_dynamicengine/libsf_engine.so" version 1.17.
Fatal Error, Quitting..

Both of these files are in the same rule set that I downloaded. I can understand a conflict between two different things that I've installed, but a conflict between two items in one package is puzzling.

So I'm figuring that the issue is that I installed Snort version 2.9.4 but could only get rulesets for 2.9.3.x. I'm looking around for an older version of Snort so I can use the only rules I can get access to, and I can't seem to find anywhere that lets me download or Am I missing something?
