long jumps not supported

Dear folks,

I am in the process of setting up my tcpdump-based filter to perform basic 
intrusion detection functions via "ra". The filter file documents all 
traffic that is allowed, prefixed by a "not" as the outer-most expression, 
so that "ra" reports all traffic that should not be present.

The filter file is approximately 700 characters long. I have reached a 
point, however, where as soon as I add a new clause to the filter, "ra" 
responds with the following error:

   ra: expression: long jumps not supported

Is my filter file too long for the program to handle? If so, how do people 
specify complex rules to the program?
