What happened to xorg-libs?

[Frank J. R. Hanstick]

Hello,
	The following occurred when upgrading:

Warning: No port xorg-libs found in the index.
To report a bug, see <http://guide.macports.org/#project.tickets>

Apparently, xorg-libs was changed to something else and I would like  
to know the steps in changing the reference or if something else needs  
to be changed?
