mrtg versus squid

       Hi, all
       
       I'm trying to run mrtg-2.5.4b to monitor our cache, but some errors are
returning from mrtg, and I don't know where to start to fix them. See:
        I have compiled squid-2.1.PATCH2 with --enable-snmp and I configured
squid.conf as well the FAQ says. I also have applied the squid patch to mrtg and
defined port 3401 in mrtg.conf as follows:
Target[httpsvc]: cacheHttpAllSvcTimeFiveMin&cacheHttpAllSvcTimeFiveMi
n:public@xxx.xxx.xxx:3401
        Every line where there is a public@xxx.xxx.xxx, I put the :3401 entry.
        Squid stars so smootly, everything goes ok...:
        .
        .
        .

        But, when I try to start mrtg (it is (will be) running just to monitor
the cache), a lot of the following block lines return to me:

        (Sorry... I must put xxx.xxx.xxx and 000.000.000.00 to the machine's
        name and IP address.)

        And, at the end, the line: Unknown SNMP var cacheServerOutKb.
        Could anybody tell me what am I doing wrong or what I didn't do yet?

        Thankyou your attention
