It looks like the problem is this:

This failure with crypt is preventing LIBLUA_LIBS from being defined,
which in turn is preventing the NSE object files from being included in
Makefile.in. Maybe you can do some research to find out what the problem
with crypt is? Try commenting out the checks against LIBLUA_LIBS in
Makefile.in:

# ifneq (@LIBLUA_LIBS@,)
NSE_SRC=nse_main.cc nse_utility.cc nse_nsock.cc nse_dnet.cc nse_fs.cc nse_nmaplib.cc nse_debug.cc nse_pcrelib.cc 
nse_binlib.cc nse_bit.cc
NSE_HDRS=nse_main.h nse_utility.h nse_nsock.h nse_dnet.h nse_fs.h nse_nmaplib.h nse_debug.h nse_pcrelib.h nse_binlib.h 
nse_bit.h
NSE_OBJS=nse_main.o nse_utility.o nse_nsock.o nse_dnet.o nse_fs.o nse_nmaplib.o nse_debug.o nse_pcrelib.o nse_binlib.o 
nse_bit.o
ifneq (@OPENSSL_LIBS@,)
NSE_SRC+=nse_openssl.cc nse_ssl_cert.cc
NSE_HDRS+=nse_openssl.h nse_ssl_cert.h
NSE_OBJS+=nse_openssl.o nse_ssl_cert.o
endif
# endif

You might still run into a crypt problem when linking.
