[Pkg-clamav-devel] Bug#923498: cyrus-imapd: fails to build against libclamav9

[Sebastian Andrzej Siewior]

Source: cyrus-imapd
Version: 3.0.8-3
Severity: Serious
Control: block 922004 by -1 

By the time we planned the transition for libclamav there was no
cyrus-imapd package which depended on libclamav-dev but this changed. I
just realised that.
The package failed to build because the ABI on clamav's side changed
between 0.100 -> 0.101:

Here [0] is an example what I did for havp. Please let me know if 
[ ] you are going to port it yourself
[ ] you ask (quick) upstream to do so
[ ] you are going to drop the support for clamav 
[ ] you want me to port it

If you have the option to use clamav's socket instead the library
interface then this is probably the better option.
