Sorry, I inadvertently left the list off my previous reply. Returning the conversation to the list now.

But usually the reason your build was interrupted the first time was because an error occurred. Retrying will probably hit the same error, only now the log will be incomplete -- it won't contain information about the parts of the build that were already done before. And if you want help analyzing why the build failed, we want to see the complete log.

No, there's just the main.log.

Yes, but the log did not contain information about every aspect of the build (indicated by the lines saying "Skipping completed"), because there had been a prior interrupted or failed build. Cleaning before building would have made MacPorts start the build over from scratch and resulted in a log of everything.

If you selfupdate every time before you sit down to install or upgrade a port, great, but if there might be a day when you upgrade or install a port without selfupdating first, you might hit this bug.

getmail-2.6 was renamed back to getmail like it should have been. See r82963. The incorrectly named "getmail-2.6" was only in the repository a few days, since r82690.

Yup. No problem there.
