Please help with cvm-vchkpw

OS: Red Hat Linux release 7.2 (Enigma)

Steps that I have followed as instructed in README.vchkpw and in
cvm-vchkpw.c:

1) http://untroubled.org/bglibs/ is compiled and installed

2) modifed conf-cc:
gcc -W -Wall -Wshadow -O -g -I/usr/local/include
-I/usr/local/vpopmail/include

3) modified conf-ld:
gcc -g -L/usr/local/lib -L/usr/local/vpopmail/lib

4) modified Makefile.  Added:
cvm-vchkpw: load cvm-vchkpw.o module.a crypt.lib shadow.lib s.lib socket.lib
        ./load cvm-vchkpw getpwnam.o module.a `cat crypt.lib` `cat
shadow.lib` `cat s.lib` `ca
t socket.lib` -lbg-net -lvpopmail

cvm-vchkpw.o: compile cvm-vchkpw.c module.h facts.h errors.h
        ./compile cvm-vchkpw.c

Also added cvm-vchkpw to the programs rule:

programs: cvm-vmailmgr-udp sql-query-test cvm-testclient cvm-checkpassword
cvm-vmailmgr cvm-qm
ail cvm-pwfile cvm-unix cvm-vmailmgr-local cvm-benchclient cvm-vchkpw



5) make

Can someone let me know whether I miss anything from the steps above ?

Thanks.
