GnuRadio Installation problems..

Greetings,

Ran into another land mine executing the following command

sudo port -d upgrade --enforce-variants libsdl +universal

result:
.....

Warning: the following items did not execute (for xorg-libXdmcp): org.macports.destroot org.macports.configure org.macports.build

Any idea how  to get the proper version of this library?

Thank you for your Help
