For a more general point of view, is MacOSX able to load multiple

(using libtools and automake) that use this method ?
...I'm having some problems with this, too: we use NSLinkModule() for
our bundle loading...when you use NSLINKMODULE_OPTION_PRIVATE, multiple
libraries defining the same (global) symbol can be loaded because each
module has it's own "namespace"...unfortunately, this made it
impossible (or rather, I haven't found a way yet) to call functions
from other loaded modules...
...when you don't use the OPTION_PRIVATE, the app will crash when a
module containing a duplicate symbol is loaded...this crash can be
avoided by using another flag,
NSLINKMODULE_OPTION_RETURN_ON_ERROR...but the module still doesn't
load...
...if it helps, this is what I'm using now:
ret = NSLinkModule( image, filename,
NSLINKMODULE_OPTION_BINDNOW |
NSLINKMODULE_OPTION_RETURN_ON_ERROR);
