hi all,
 	i m trying to compile sample program given along with slack
lib. but it gives following error.

 	/usr/local/lib/libslack.a(pseudo.o): In function `pty_open':
 	pseudo.o(.text+0x1c6): undefined reference to 'openpty'
 	collect2: ld returned 1 exit status

 	i m working on Red Hat Linux release 7.0 (Guinness) machine.
kernel is 'Kernel 2.2.16-22 on an i686' and C lib is
'GNU C Library development release version 2.1.92, by Roland 
McGrath et al.'

 	what is the problem? will i have to upgrade my libc?
