uninstall/reinstall checkpassword troubles "errno"

Hello,

I have been having trbls with checkpassword, I actually noticed I may not 
even have it installed correctly, as I went to /bin and there was no 
"checkpassword" file, only directory with source.  there is a "cmd5checkpw*" 
file, will this cause conflict, my qmail pop3d run script does not reference 
it, it looks for /bin/checkpassword.

   Anyway, I want to reinstall checkpassword, however, when I make I get the 
following error:

[root@localhost checkpassword-0.90]# make
./load checkpassword prot.o unix.a byte.a  `cat \
shadow.lib` `cat crypt.lib` `cat s.lib`
checkpassword.o(.text+0x6e): In function `main':
: undefined reference to `errno'
checkpassword.o(.text+0xf9): In function `main':
: undefined reference to `errno'
checkpassword.o(.text+0x247): In function `main':
: undefined reference to `errno'
unix.a(pathexec_run.o)(.text+0xf6): In function `pathexec_run':
: undefined reference to `errno'
unix.a(pathexec_run.o)(.text+0x167): In function `pathexec_run':
: undefined reference to `errno'
unix.a(alloc.o)(.text+0x4c): more undefined references to `errno' follow
collect2: ld returned 1 exit status
make: *** [checkpassword] Error 1

Any ideas on how to properly uninstall/reinstall.  I think this bad original 
checkpassword setup may be the cause of my qmail "-ERR unable to write pipe" 
problems.

Thanks in advance.
