I've been doing research into this for Perian, and we've determined  
that this is the case. In general, we've found that -mdynamic-no-pic  
can't be used for any kind of loadable module (shared library,  
Bundle, etc).
We're looking into potential workarounds, but I don't know offhand  
what those are as I've been having to work on schoolwork instead of  
OSS recently.
