Thankyou for sending the report.

It might first be worth asking: *why* does Portage set TMPDIR, and what
are the consequences of routing around it?

Please, when you're making patches, consider what impact they will
have on people not using Gentoo, or even people who are compiling on
Gentoo but not through ebuild.  (People do sometimes build their own
