[Dovecot] Problems running Dovecot 1.2.17 on AIX

[ra at rz.uni-frankfurt.de]

Hello,

we have a problem getting Dovecot 1.2.17 to work on one of our 
AIX-Machines (AIX 5.3). Dovecot compiles fine, but if we try to run it 
we get strange library dependency problems such as the following:

[root at localhost dovecot-test]# /local/dovecot-test/sbin/dovecot -F -c 
/local/dovecot-test/etc/dovecot.clients.conf

Edlopen(/local/dovecot-test/lib/dovecot/imap/lib01_acl_plugin.so)

FCouldn't load required plugins

We tried to use the compiler-script as described on the wiki 
(http://wiki1.dovecot.org/AixPluginsSupport) and we tried to compile 
dovecot with gcc instead of xlc. We even tried it on another host 
running AIX 5.3 but dovecot still fails with the runtime linker 
complaining about missing runtime definitions. Any hint/help would be 
appreciated.

Thanks in advance
