$ cvs checkout -D 'May 21 02:10' mercury

I haven't tried it, but I think this should work.
(One caveat: it is possible that you might have to convert the
date/time to GMT, i.e. -D 'May 20 16:10'.)

Note that this will give you the last version that bootstrapped *and*
passed all the tests.  If you just want the last version that
bootstrapped, check the dates on 
/home/mercury/public/test_mercury/logs/installed.* and use those
instead.

This is a good idea, which I have been considering for a while but have
not yet gotten around to doing.

However, neither tagging nor using dates as described above will catch
all the problems, because some problems are architecture-specific.
For example, I recently upgraded to version 4.13alpha1 of the Boehm
collector, which as it happened broke on both Linux 1.3.x and
Irix 5.x; but it worked fine on dec-alpha-osf3.2.
So it may be worth checking the dates on
/home/mercury/public/test_mercury/logs/installed.*
anyway.
