some ports want to compile with icc

[mein name]

Hi!
Some ports (e.g. clamav or lighttpd) want to compile with the icc, even if I don't select
it in my make.conf or somewhere else. I tried to set the gcc as
default compiler with CC=gcc but this doesn't change anything. If
I deinstall the icc I get an error while compiling clamav like this:


icc: not found
*** Error code 127

Stop in /usr/ports/security/clamav/work/clamav-0.90.3/libclamav.
*** Error code 1

        ! security/clamav       (new compiler error)

Any suggestions?
