It looks like gcc9 did in the mean time build on that builder.

I've previously used Grand Perspective to examine the disk space usage of the build machines and didn't see anything big, but it turns out Grand Perspective doesn't include items whose names begin with a period, and that's where the problem was: the .Spotlight-V100 directory on the 10.7 builder was 36GiB the first time I looked and 26GiB the second time I looked, and on the 10.8 builder it was 16GiB. I've deleted the Spotlight indexes on all the builders and hopefully when they're done rebuilding they'll be smaller.

Maybe I should just exclude /opt/local and /Applications/MacPorts from the Spotlight indexes on the builders, but I wasn't sure if that would have some undesirable effect on some build system (Xcode?) that might use Spotlight to find something?
