[clamav-users] 0.98.5 installation error

[nikos]

Hello list
I try to install 0.98.5 from source as I always do, and I got the error:
ERROR: This tool requires libclamav with functionality level 79 or
higher (current f-level: 77)
The previous version  0.98.4 was working without problems and install it
again.
I run centos-release-5-11.el5.centos and many other servers with old
fedora version, other with centos 6.
How can I solve this problem before upgrade all servers I admin?
Thank you in advance.
Nikos
