ЭТО из-за libpng.
Кажется мы выловили эту самую ошибку...
http://libpng.sourceforge.net/
UPDATE 20 August 2004: In the rush to get libpng-1.2.6 out to solve the
vulnerability described below, a bug was introduced that causes almost
all PNG output files to be written with incorrect zlib header bytes.
A patch has been posted along with the libpng-1.2.6 sources, and
libpng-1.2.7 will fix this problem.

пересобраться пакетам perl-GD* не помогает...

Помогает, но не целиком. Вернее, целиком, но не полностью. :)
Если приложить этот патч, то число успешных тестов возрастает (GD2):
Failed 1/2 test scripts, 50.00% okay. 8/11 subtests failed, 27.27% okay.
Failed 1/2 test scripts, 50.00% okay. 3/11 subtests failed, 72.73% okay.

Разобрался. Этот патч состоит из 2 частей: первая часть добавляет код,
который занимается оптимизацией (уменьшением) zlib_window_bits; вторая часть --
полностью убирает код оптимизации, который появился только в 1.2.6 (и о
котором, по-видимому, речь идет в анонсе).
Если приложить только вторую часть патча (которая убирает оптимизацию),
то все тесты perl-GD* проходят.
С другой стороны, тетсы состоят в том, что с помощью GD создается
изображение и сравнивается с эталонным файлом (который был создан
с помощью более ранней версии libpng). Так что, возможно, новые
изображения вполне корректны, просто они не совпадают с эталонными
файлами.
