 Hmm, the log says:

 This is curious because I don't see why cmake would be trying to use
 libnotify. It's not listed as a dependency in the port, and I see no
 mention of libnotify in the compile line.

 We've seen this once before, in #30697. That was also on Lion, also with
 llvm-gcc-4.2. There, the solution was to uninstall libnotify, which I
 recommend to you as well. Or if you actually need libnotify (or another
 port you've installed does), then the workaround would be to reinstall
 libnotify with the universal variant, i.e.:

 {{{
 sudo port upgrade --enforce-variants libnotify +universal
 }}}

 The fact that MacPorts chose to compile with llvm-gcc-4.2 instead of clang
 also suggests you are running Xcode 4.0 or 4.1; consider upgrading to
 Xcode 4.6.3.
