Bug 556464 – sys-apps/portage-2.2.20: emerging tbz2 fails with AttributeError: 'str' object has no attribute 'build_id'

• Status: RESOLVED FIXED
• Product: Portage Development

[Description S. Gilles 2015-08-01 20:05:24 UTC]

Building a package as by `ebuild ... package`, or by `emerge --buildpkgonly ...` works as expected, but installing the resulting .tbz2 fails.

Reproducible: Always

Steps to Reproduce:
1. emerge --buildpkgonly sed
2. emerge sys-apps/sed-4.2.2.tbz2

alternately

1. ebuild /usr/portage/app-editors/nano/nano-2.4.2.ebuild package
2. emerge app-editors/nano-2.4.2.tbz2

Actual Results:  

These are the packages that would be merged, in order:
