You have to look in the image where the primitive is called, you'll
have a line like
<primitive: 'primitiveName' module: 'PluginName'>
That module name is used to find the plugin, see
It tries to load the name as given, or with a "lib" prefix and ".so"
suffix" (and ".dylib" for MacOS X).
Also it tries to find it in "./", $SQUEAK_PLUGIN_PATH, "/usr/local/
lib/squeak/3.9-8/", $LD_LIBRARY_PATH, and the system standard library
directories ("/usr/lib" etc.).
If all that fails, it looks if this is an internal module.
