Missing crypt in Pine compile?

[Dwight Johnson <dwj@aaronsrod.com>]

My Pine compile attempt is showing:

cc    -g -DDEBUG   -DLNX -DSYSTYPE=\"LNX\" -DMOUSE -o pine addrbook.o adrbkcmd.o adrbklib.o args.o bldaddr.o context.o filter.o folder.o help.o helptext.o imap.o init.o mailcap.o mailcmd.o mailindx.o mailpart.o mailview.o newmail.o other.o

../c-client/c-client.a(osdep.o): In function `checkpw':
/usr/src/pine4/pine4.21/imap/c-client/osdep.c:106: undefined reference to `crypt'
collect2: ld returned 1 exit status
make: *** [pine] Error 1

I tried installing the 'mailcrypt' package, but that wasn't it.

Thanks in advance for what package to install,
