In that bug the Gentoo MySQL maintainer says that adding -fPIC is not  
a good idea:

http://bugs.gentoo.org/show_bug.cgi?id=238487#c34

He says building a shared library would be better, and I know shared  
libraries are greatly preferred over static ones on Mac OS X. So we  
should do that, if we can figure out how, or convince MySQL AB to do  
so in a future version of MySQL.
