That's the 10.7 builder (darwin 11), not the 10.11 builder.

The log says:

I'm not familiar with this error. I don't know what xcrun_db is (I presume it is used by xcrun), in what way it might be corrupt, or how that corruption might be fixed. Do you have any suggestions?

Maybe it was corrupted because it was truncated because it could not be fully written because the disk was full; as you know, we are low on disk space on these builders. We should try having the build system uninstall unneeded ports on an ongoing basis, as in https://trac.macports.org/ticket/57464

The 10.5 machine crashed in some way, and it has not been able to boot up after that. I spent some time with it last night and was not successful at getting it to boot up, though I was able to repair the disk and was able to use the disk to boot up a different Power Mac. I'll give it another try later.
