[Clam-devel] how to Ladspa Plugin ?

[globot]

hi,

i have a stupid question today,
I made a network using NE, there is ladspa plugin inside. But when i 
load this network with my sotware have an error message :
"Error creating a processing object of type 'hpf1' which is not available."

'hpf1' should be a "Simple High Pass Filter" (id: 1042 or 1052)

So is there something special to do to automaticly scan ladspa plugin ? 
like NE do... Because i don't have any messages telling me . "[LADSPA 
Plugins] looking at path '/path' "
