[Csnd-dev] problem with rtalsa

When I try to use csound in real time using rtalsa I get errors

 unknown rtaudio module: 'alsa', using dummy modulertaudio: dummy module enabled
writing 512 sample blks of 64-bit floats to dac:hw2,0

but librtalsa.so exists and has no missing references

what am I missing?
