...I'm hoping to get an intel mac after I get my current projects  
done, so you're really going to have to depend on pd's and apple's  
documentation to get this going...

...no:  I didn't even realize that there was an external [loader]  
until now (ie. I had no problem loading externals when I first built  
pd last summer on the preview intel macs)...unfortunately I just  
don't have time to help here...

...I believe this externals/loader/import object is only tested with  
pd-0.38-4...and you shouldn't need it unless you want to experiment  
and help hans work on namespaces...

...sure, there's tons of sample code, but chris and I only have so  
much time...in other words, we accept patches, or large sums of  
money ;-)
