runstatedir causes error, it is not clear where run directory without it is.

You said build with following command on readme but it is not working:

[root@localhost munge]# ./configure --prefix=/usr                 --sysconfdir=/etc             --localstatedir=/var          --runstatedir=/run       
configure: error: unrecognized option: `--runstatedir=/run'
Try `./configure --help' for more information
[root@localhost munge]# ./configure --prefix=/usr          ^C     --sysconfdir=/etc             --localstatedir=/var          --runstatedir=/run       
[root@localhost munge]#

    Remove GCRYPT_VERSION from gcry_check_version

Without --runstatedir=/run , it continues but it is unclear where the runstatedir would be.

I suspect you're using a version of autoconf prior to 2.70 (see autoconf --version). The --runstatedir option is only available if the configure script was generated with autoconf-2.70 or later.

However, you can also append the configure line with either --with-runstatedir=/run or runstatedir=/run.

If you're watching the configure script output, towards the top you should see something like:

checking for runstatedir... /run

After running configure, you can check the resulting config.log:

$ egrep ^runstatedir config.log
runstatedir='/run'

If runstatedir is not specified, it will default to ${localstatedir}/run.
