HitFreqsRuleTiming.pm question

[Ralf Hildebrandt]

I tried installing the "HitFreqsRuleTiming.pm" Plugin in
SA/Amavis by adding 

loadplugin HitFreqsRuleTiming /etc/mail/spamassassin/HitFreqsRuleTiming.pm

to /etc/mail/spamassassin/v340.pre

The plugin is being loaded:

May  6 13:22:56 mail amavis[29801]: SpamAssassin loaded plugins: ASN,
AWL, AskDNS, AutoLearnThreshold, Bayes, BodyEval, Check, DCC, DKIM,
DNSEval, FreeMail, HTMLEval, HTTPSMismatch, Hashcash, HeaderEval,
HitFreqsRuleTiming, ImageInfo, MIMEEval, MIMEHeader, RelayEval,
ReplaceTags, Rule2XSBody, SPF, SpamCop, TextCat, URIDNSBL, URIDetail,
URIEval, VBounce, WLBLEval, WhiteListSubject  

but I'm not getting any output (I even patche the plugin to use
/tmp/timing.log) file. Why?
