You are misreading the error message.  Those 'dbg:' messages are
printed by SpamAssassin.  SpamAssassin is executing dccproc.  There
is something wrong with /usr/bin/dccproc - Perhaps a bad link or the
file does not exist or bad permissions (etc).

Either make sure that dccproc is correctly installed in /usr/bin, or
change the dcc_path in your SpamAssassin configuration file, eg:
  dcc_path /usr/local/bin/dccproc

You should be able to feed a message by hand into dccproc, eg:
  /usr/bin/dccproc -H -x 0 < msg
and you should get a X-DCC header.
