This list is fine.

It seems like that blocker should have been solved automatically.
Can you reproduce it and post emerge output with the --debug option
enabled?

When a package is not uninstalled automatically, there are a number
of possible cases that can trigger it:

1) The package cannot be installed because it has been pulled in as
a dependency of a package or a package set such as system or world.

2) The package can be uninstalled, but due to a case of bug #1343
involving an || dependency, it has been pulled into the dependency
graph. This can be solved automatically if the package is masked in
package.mask.

3) The package needs to be uninstalled before a conflicting package
is installed, rather than after, due to a !!atom blocker (bug #250286).

4) The EAPI is 0 or 1 and the package conflicts with either a system
package or a direct runtime dependency of the running
sys-apps/portage instance. This case is handled similarly to case 3
above.

None of the above cases seem to apply to your gnome-base/gail
blocker, but --debug output might provide a clue. With
portage-2.1.6.1, the --debug output now includes a representation of
the digraph which makes it easier to recognize instances of case 1.
