[Dovecot] antispam plugin troubleshooting

[Bradley Giesbrecht]

I built the dovecot antispam plugin and renamed it so I could have  
multiple backends installed at the same time.
http://johannes.sipsolutions.net/Projects/dovecot-antispam

I tried recompiling antispam without renaming the .so and I get the  
same result indicated below.

All other plugins and the system as a whole has been functioning  
normally. Only when I add antispam plugin does dovecot not start and  
perform as expected.

What can I do to find the reason dovecot is not loading  
lib90_antispam_mailtrain_plugin.so successfully?

Below is some info I could think to supply for help.
