I have confirmed that following instructions with c3a16c32.

# showmount one
Hosts on one:
# mkdir /tmp/mnt
# mount one:/one /tmp/mnt
# showmount one
Hosts on one:
# umount /tmp/mnt
# showmount one
Hosts on one:

And the test set has started running.
It will take a couple of days to finish.

by the way, I did following instructions to build RPM packages on a CentOS 5.6 x86_64 host.

# yum install python-ctypes ncureses-devel readline-devel libibverbs-devel
# git clone -b c3a16c32 ssh://<my_id>@git.gluster.com/glusterfs.git glusterfs-3git
# tar zcf /usr/src/redhat/SOURCES/glusterfs-3bit.tar.gz glusterfs-3git
# rpmbuild -bb /usr/src/redhat/SOURCES/glusterfs-3git.tar.gz
