clamav 0.90.2 problem

[Claude Gagné]

Hi,

I've got a little problem with clamav. Freshclam seems to update just 
fine but I got this error message at the end of the update when running 
it with root:
ClamAV update process started at Mon Apr 30 10:30:55 2007
main.cvd is up to date (version: 43, sigs: 104500, f-level: 14, builder: 
sven)
daily.inc is up to date (version: 3184, sigs: 8782, f-level: 15, 
builder: sven)
LibClamAV Error: Database Directory: /usr/local/share/clamav not locked

The permissions on /usr/local/share/clamav:
drwxrwxr-x 3 clamav clamav 4096 2007-04-30 10:29 clamav

I installed clamav with the package install-Clam-0.90.2-SA-3.1.8.tar.gz 
found on MailScanner website. Anyone knows what's the problem ?

Thanks !
