I am using LMMS 0.4.5 on Ubuntu jaunty 64 bit. Browse ladspa plugins in Tools shows lots of items but none of these show up in LMMS, instrument plugins only lists the standard install items. There is a tip on the wiki for adding a link to the 64 bit folder but the browser shows them whether the link is present or not and the plugins are not listed whether the folder link is present or not.

I am obviously missing something here, but how do I add ladspa plugins to LMMS?
