You've pasted a lot of irrelevant terminal output above. The ultimate error appears to be that aspell failed to build. It's impossible for us to know why this happened unless we see aspell's main.log file, so please attach it.
The output also included this very important message:
Warning: xcodebuild exists but failed to execute
Warning: Xcode appears to be installed but xcodebuild is unusable; some ports will likely fail to build.
Warning: You may need to run `sudo xcode-select -switch /Applications/Xcode.app`
You should follow this suggestion, and if you need further help getting xcodebuild to work properly, write to the macports-users mailing list.
