Don't know if Zydeco is checking this thread, but the error is probably due to him linking against a newer library. Console.app says:

Dyld Error Message:

Library not loaded: /usr/local/lib/libiconv.2.dylib

Referenced from: /sbin/mount_fusefs_hfs

Reason: Incompatible library version: mount_fusefs_hfs requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0

This was on 10.6.4 as well.
