You noticed the trick ;-) Those song level values are just dummy values 
generated to demonstrate Annotator capabilities to adapt different kinds of 
data. In fact, this extractor was originally fully random and later we added 
real descriptors: lowlevel mpeg7 descriptors and song level metadata (coming 
from the id3 tags if present). But some dummy attributes are still there. 
Sorry if that has puzzled you.

It should. Clam currently comes in 4 modules (clam_core, clam_audioio, 
clam_processing, and clam_vmqt). Each one has independent scons targets:

$ scons install_core install_processing install_audioio

The only problem with that is that the configure still depends on having 
qt-devel installed. It might work without qt-devel by quoting most vmqt 
occurrences on CLAM/scons/libs/SConstruct. No guaranties though.
