The code that does the check is this:

  struct group *grp = getgrnam ("mail");
  if (!grp || (grp->gr_gid != getegid ())) die ("not setgid mail",EX_USAGE);

The only way I can see that failing is if getgrnam() failed to look up
the "mail" group, or if the gid of mlock doesn't match the gid returned
by getgrnam().  Is it possible you have two "mail" groups?  Compare the
output of "ls -ln" and your /etc/groups file.  Splitting that if() into
two parts with separate error messages will also tell you which test is
failing.
