modules_path(talloc_tos(),SAMBA_SUBSYSTEM_GPEXT) returns '/usr/local/samba/lib/gpext' which does not exist

Hello,
char *modules_path(TALLOC_CTX *mem_ctx, const char *name)
{
        return talloc_asprintf(mem_ctx, "%s/%s", get_dyn_MODULESDIR(),
name);
}

get_dyn_MODULESDIR()?
# vim ./buildtools/wafsamba/wscript
    opt.add_option('--with-modulesdir',
                   help=("modules directory [PREFIX/modules]"),
                   action="store", dest='MODULESDIR',
default='${PREFIX}/modules')

# make show_waf_options
   --with-modulesdir=MODULESDIR
    --with-pammodulesdir=PAMMODULESDIR

if i provide /usr/local/samba/lib/private/ then also gpext inside it
does not exist!

Thanks
Amit
