Asterisk won't start with chan_sccp loaded

Asterisk Asterisk Support

Asterisk 1.2.17
chan_sccp-20060408

If I compile chan_sccp answering ‘yes’ to build the PARK and PICKUP functions, Asterisk refuses to start with the following:

[chan_sccp.so]Apr 5 16:57:32 WARNING[17942] loader.c: /usr/lib/asterisk/modules/chan_sccp.so: undefined symbol: ast_park_call
Apr 5 16:57:32 WARNING[17942] loader.c: Loading module chan_sccp.so failed!

If I choose ‘no’ to both, Asterisk will start fine.

Any ideas?
