The snapshot sometimes has validation errors
because developent introduces bugs.

In general there's no easy way to isolate those bugs to installation
or code errors.  You need to diff the traces and look at the code.

There are daily runs of the validation suites automatically posted to
the web (see the validation web page).  I encourage casual users of
the snapshots to pull down snapshots on days with passing validation
runs.  (Unfortunately, the validation runs are not always sync'ed with
the time snapshots are taken.)

Recent snapshots may require updating tclcl to its snapshot.
(This is the source of some recent problems in webcache, for example.)
