I attempted compiling a ComBot (IRC Bot). i had absolutely no problems
until the  end where it put the object files together:
---cut here---
# make
cd source; make
gcc -O2 -s -Wall  -o ComBot main.o combot.o cfgfile.o parse.o com-ons.o
fileio.o
 send.o  ctcp.o server.o channel.o chanuser.o userlist.o dcc.o function.o log.o
debug.o memory.o match.o commands.o vars.o structs.o
function.o: Undefined symbol `_crypt' referenced from text segment
function.o: Undefined symbol `_crypt' referenced from text segment
*** Error code 1

Stop.
*** Error code 1

Stop.
#
---cut here---
If anyone knows a simple way to alleviate this problem, I'd really
appreciate it.
thanks a lot!
