Problems with ClamAV v0.90RC

Please note that as of writing you should not upgrade ClamAV to v0.90RC. The Mail::ClamAV perl module (v0.17) will not compile with this version of ClamAV installed and will therefore break MailScanner.For now you should remain on ClamAV v0.88.5 until either the ClamAV or the Mail::ClamAV developers resolve the issue.
