asterisk users - Oct 2005 - chan_capi.so: undefined symbol: ast_smoother_feed

Hello,

i have installed Asterisk Version 1.2 from source on Sarge with a 2.6.8
Kernel. Then i did a "apt-get install libcapi20-2".

When i start asterisk, i get this error:
------------------------------------------------

Is my capi module too old?

Thanks, Mario
