We close tickets when we fix them, and we only keep one ticket open for a given issue, so since your build failure was a duplicate of another ticket, we closed it in favor of the earlier one, and the earlier ticket closed when its fix was committed to the repository.
We use one ticket per issue, so when, after resolving the build failure, you encountered a new problem, that needed to go in a new ticket, so we'll use this ticket to track that issue now, although I guess there are two new issues: the failure to launch and now, after reinstallation, the failure to activate.
Normally, /opt/local/var/macports is hidden in the Finder. You can press Command-Shift-Period in the Finder (or use other means) to see hidden items, but you also don't need to do that. To attach the log you can also just copy the full logfile path to the clipboard, then click "Attach another file" and "Choose File", and in the file chooser, press Command-Shift-G to bring up the Go panel, paste in the logfile path you copied, press Return twice, and click "Add Attachment".
