Hi,

Let's stick to 2.x versions, first...

Thanks, that looks already pretty promising. ;-)

It does: "temp_install: creating temporary installation" means it's  
running make install in the background.

That counts as a bug. I also get that from time to time (and with  
Postgres-R testing on 3+ instances, it's even more annoying).

Note that the error just before that is, that a psql process it starts  
cannot connect to its postmaster ("startup of test test-conn-0A  
failed, skipping.") Please check the log  
(src/test/regress/dtester.log) for why that failed in the first place.  
Can you connect manually to the database (that's still running after a  
make dcheck)?

I'm not exactly a distutils hacker... Anybody else got any clue here?

I'd rather suspect that more of them will arise.
