check_swap works by running the swap command. This is my output on a 
Solaris 9 server:

bash-2.05$ ./check_swap -v -v -v -w 10% -c 5%
Command: /usr/sbin/swap -s
Format: %*s %*dk %*s %*s + %*dk %*s = %dk %*s %dk %*s
SWAP OK: 80% free (893 MB out of 1129 MB) |swap=893MB;112;56;0;1129

My guess is that configure did not pick out your correct swap command. 
Can you send your config.log file?

Right you are. I've committed v1.26 with better help and usage output. 
Thanks.
