svn-1586 Openbsd 4.3 Could not load plugins

Hi, i’ve just installed svn-1586 on OpenBSD 4.3, works like charm (after the STRCASESTR hack in the config.h) except i cant load any plugin.
If the plugin are presents with the .so.0.0 extention:

root@erpto /usr/local/mt-daapd/lib/mt-daapd/plugins # mt-daapd -m -D plugin -d 9 -f

Config entry general/compress is deprecated.  Please review the sample config

with the plugins renamed to .so:
