during a portmaster upgrade
I see you are using Portmaster. You might try ports-mgmt/synth or ports-mgmt/poudriere for building ports. They are much more reliable and do not affect the live system as the packages built are installed from a local repository. There is a little work necessary to get this up and running, but after that maintenance of the ports makes less headaches and it is fun if you have to update multiple systems.
