I should have looked closer at what was going on before I posted. It appears that forums-forums-create.sql is getting loaded twice. It is loaded once from the forums-create.sql script and then the apm is loading it a second time. I unchecked the forums-forums-create.sql file before I installed the package and it completed successfully.
Unforunately, I can't really test it from there because I think the cvs site-map is broken: I can't create new folders.
I'll update again once I can get a version of cvs that works.
