[gentoo-portage-dev] Rerunning src_test with modifications

[Mike Gilbert]

When I run into test failures in www-client/chromium, the normal
procedure is to file a bug and filter the failing tests until the
problem can be fixed (usually upstream).

Ideally, I would like to be able to do the following:

1. Start building chromium using emerge or ebuild.

2. If src_test dies, modify the ebuild to filter the failing tests.

3. Re-run the test phase without rebuilding the source code.

If I do not run ebuild clean, portage re-uses the environment from the
previous run, which does not include my changes to the ebuild.

Is there an easy way to have portage source the modified ebuild
instead of just using the previous environment? Wiping out the
environment file isn't really an option because we set some global
variables in pkg_setup.
