A checkout from a given repository is performed with a command like this:
# svn checkout https://svn.FreeBSD.org/repository/branch lwcdir
# svn checkout https://svn.FreeBSD.org/ports/head /usr/ports
After the initial checkout, the local working copy can be updated by running
# svn update lwcdir
To update /usr/ports created in the example above, use:
# svn update /usr/ports
An alternate way of updating the local working copy after checkout is provided by the Makefile in the /usr/ports, /usr/src, and /usr/doc directories. 
Set SVN_UPDATE and use the update target. For example, to update /usr/src:
# cd /usr/src
# make update SVN_UPDATE=yes

Install sudo using port, type:
# cd /usr/ports/security/sudo/ && make install clean
