I recently tried updating glib2, and I get the following error:

--->  Fetching archive for glib2
--->  Attempting to fetch glib2-2.54.2_1+x11.darwin_16.x86_64.tbz2 from https://packages.macports.org/glib2

and if I look at the log file, I see:

We've seen this error before from users whose /tmp directories had acquired incorrect permissions; see #50867. Can you check your /tmp directories' permissions and fix them if they're wrong?
