Neither so-called pragmatic nor testing-by-hand are good testing methods.
"Pragmatic" is not a testing method at all; testing by hand involves too
much of human error when the package count is larger, than, say, 3 - 5.
Automated tests units should be provided by packages (and, well, some do
provide them, some don't) -- see . For X11
application I would just simply run it (well, that implies having X on the
build host; bulk-running a 3rd party apps would also make buildhosts less
secure) -- if the app won't segfault after a given time (well, they tend to
have longer and longer start-up time), it propably means it is working good
enough to release it to the world. There are unit tests implemented in
Python, that claim to be able to test a GUI application too, but I haven't
tested any yet.

Of course, this would take a lot of RAM, CPU and time to perform. But I am
perfectly sure, that good, automated unit tests are the only way to
drastically reduce bug count before actually releasing a binary package.

And where would you hold INCOMPATIBLE_WITH ? In Makefile? That's not a good
idea. Only in binary package? More hand-work needed to build a set of binary
packages, greater bug possibility.

Jeremy could also update libtiff, rebuild only amd64 packages, that needed
it and "silently" upload them to ftp (without a rev bump) and e-mail
port-amd64@ about the binary packages.

Why amd64 owners should use binary packages anyway? I bet they can build
mozilla in the same time, that my machine needs to install a binary package
of it :)
