Building cairomm (inkscape dependency) fails

[Jason Merrill]

I've been trying to get the latest version of inkscape going, and I've
run into some trouble installing cairomm:

Error: Status 1 encountered during processing.

Can anyone offer any advice?

One thing I should mention is that I had an old ports tree, which I
kind of messed up, so I just moved the entire /opt directory to
/oldopt.  I figured this would be an okay thing to do, but I've
encountered a couple conflicts in cases where macports put things in
directories other than /opt.  For instance, aquaterm gets put in
/Applications/Macports/Aquaterm.app, and also sticks something in the
/Library directory.
