I will probably when there is time write up (don´t know when, but hopefully the coming month) something on the declaring of libraries and externals when I get time. This has been one of the more troublesome thing to understand for me as former Pd Extended user where everything "just worked" migrating tp Pd Vanilla. Now using Vanilla which I am verry happy for I still see alot of questions regarding how to install things, and then how to use it. I found these pages useful as some sort of summary - and tracker of old libraries - among with what is written up in the FLOSS manual. 

Sharing these pages here, if someone is getting the idea and time to to some update managings:

http://en.flossmanuals.net/pure-data/list-of-objects/glue/  and continuing on the next pages in FLOSS

All the best,

Björn
