This nails it. We need bugs to be specific, on the point. Any such generalized
meta-bug that could affect all or none (both is not true, as the information
provided already shows) can't be handled.

Please observe your install behavior and try to report the issue with lang
package on a specific package (one bug per issue - collection bugs will hardly
ever reach any reasonable conclusion)
