In the meantime, how about the following:

In default non-verbose mode, silently memoize
the list of packages that were not found. Then,
only if something goes wrong, say something like:

"The package failed to build. Perhaps the reason
is that one of the following packages was not found:"

In non-default verbose mode, behave as now.
