When emerged with USE=ldap, dovecot fails to load LDAP plugin, it works it this plugin isn't used, and dies if it is.

In the ebuild Dovecot is configured using --with-ldap=plugin changing it to just --with-ldap should solve the problem. I experimented with building Dovecot from sources before the ebuild was published and had the same problem. I saw an article somewhere on the dovecot site saying that =plugin is for distributing binary packages with the ldap libraries in a separate package, so perhaps the ldap libraries made by =plugin are just stubs. Unless there is a clever way of configuring the ldap support that I couldn't find;). However using the --with-ldap option seems the simplest way as then it just works! BTW A similar problem may exist with sql support as that is configured the same way.
Fix added into cvs. Worked for me.
