The Priority field is for use by Macports team members only.

[ryandesign (Ryan Carsten Schmidt)]

The transcript you provided shows an unclean build attempt. Please ​clean and try again. If it fails again, attach the complete main.log file.

Please remember to use WikiFormatting when writing in Trac.

When filing a ticket, fill in the Port field; don't put the port name into the Keywords field.

No need to Cc yourself when you are the reporter.

[ryandesign (Ryan Carsten Schmidt)]

Can you attach the main.log file, please, as requested above? Without it, we cannot investigate why this failed for you.

[smithsp (Sterling Smith)]

I am going to attach my own main.log, since I am also getting a build error for bootstrap-lean.

[smithsp (Sterling Smith)]

main.log (last 40k lines to not exceed size limit)

[ryandesign (Ryan Carsten Schmidt)]

I don't deal with incomplete logs. Please attach the entire main.log. Compress it first (xz, bz2, gz, zip, etc.) so it doesn't exceed the size limit.

[mf2k (Frank Schima)]

No response from reporter. Builds on the buildbot.
