HAVP after Squid deletion

[judex]

Hopefully someone can give me a hint on that:

I had running squid in transparent mode together with HAVP. Then I decided I would not need any proxy cache and wanted to use HAVP standalone in transparent mode after squid deletion.
This is not working any more ->

p: : Havp: Squid is already configured as transparent proxy. Use 'Standard' proxy mode.

I already deleted everthing I found with "squid" in it with

find /* | grep -i squid | xargs rm -r

and reinstalled HAVP. Still the same error message. If I run HAVP in standard mode it works.

/tmp/rules.debug has no entries under that line

havp proxy ifaces rules

Also deleted /tmp/config.cache

Anybody?
