Hmm, yes, this is a trickier case.
The problem appears to be the fact that the Makefile's
`patchpackageconf` helper `mv`'s over the .conf file installed via
`install` with a file create by the shell. I'll reopen #21965 and post a
fix shortly.

Out of curiosity, have you set umask to 077 intentionally or is this
somehow accidental? This does seem like a very strange configuration
(although GHC should work nevertheless).

Cheers,
