Hmm. The sample report you attached is for a Skyrim.app. I'm guessing you're using some sort of wrapper, like Wineskin. First, if that wrapper has any custom patches rather than using vanilla Wine, we won't be able to help you here.
You are right, for convenience I have packaged a simple script as an app and this script actually uses wine-devel from MacPorts. It looks like this:
~/Applications/Skyrim.app/Contents/MacOS/Skyrim: !/bin/bash exec /opt/local/bin/wine 'c:\Program Files\Steam\Steam.exe' -applaunch 72850
Second, you sampled the wrong process. You sampled process 215, which is the one running Steam.
Sorry, this is also true. after reading your first post I looked for a process that consumed CPU and then accidently sampled Steam.
