update to "Following -current": changes to expat und sudo

Hi,

marc@ has aswered theese on ports@ about 5 times in two weeks,
so I think the threshold for a FAQ is reached ;)

This adds the recent change in sudo environment handling and
the somewhat less recent move of libexpat from the ports tree to xenorca
to www/faq/current.html.

have fun

+<h3>2007/05/10 - ports are using the libexpat shipped with xenocara</h3>
+<p>
+The textproc/libexpat port has been removed from ports dependencies,
+now all ports use the libexpat that's shipped with xenocara.
+<p>
+This means that for a number of ports to work you need to have <tt>xbase</tt> installed.
+Refer to the <a href="file://localhost/usr/www/faq/faq4.html#AddFileSet">FAQ</a> 
+on how to add <tt>xbase</tt> to a an installed system.
+<p>
+Ports affected by this include bash, mutt and all ports with devel/gettext as a dependency.
+<p>
+This affects package installation as well as ports builds.

+Sudo(8) will by default reset the environment to a small default set
