I believe there was something I needed to set in the makefile... NOCRYPT=???, wasn't there? Or is it something else...

The relevant parts of my makefile are:

#Uncomment the line below if you are getting implicit decleration of re_exec
#REG = -DREGEX

#Uncomment the line below if you are getting undefined re_exec errors
NEED_REG = -lregex

#Uncomment the line below if you are getting undefined crypt errors
NEED_CRYPT = -lcrypt

It still has the error... here is my makefile.

CC = gcc
#PROF = -p

#SOLARIS_FLAG = -Dsun -DSYSV
#SOLARIS_LINK = -lnsl -lsocket

#Uncomment the line below if you are getting a line like:
#interp.c:757: warning: int format, time_t arg (arg 7)
#TIME = -DTIMEFORMAT

#Uncomment the line below if you are getting implicit decleration of re_exec
REG = -DREGEX

#Uncomment the line below if you are getting undefined re_exec errors
NEED_REG = -lregex

#Uncomment the line below if you are getting undefined crypt errors
NEED_CRYPT = -lcrypt

#DBUGFLG = -DREQUESTS

#Uncomment the line below if you want a performance increase though beware
#your core files may not be as much of a benefit if you do.
