[Dovecot] Issues when compiling dovecot antispam on debian wheezy

[Joan]

I've been trying to compile the latest version of dovecot-antispam, and it
doesn't work, the latest patch fixes compilation for dovecot versions
greater than 2.1.16 but the packaged version in debian is 2.1.7 and doesn't
provide the DOVECOT_PREREQ macro.

It seems there are some solutions:
1) Rollback to the last working version so it can be used on wheezy
2) Open a bug report in debian to see if they can backport the macro here (
http://www.dovecot.org/list/dovecot-cvs/2013-March/022903.html)
3) Use the packaged version from debian
4) ..

What's your opinion?
