Чтоб хоть где-то было зафиксировано.

В alterator-lookout 2.7-alt1 оставался досадный ляп: патч для guile20
применяется под %ifarch e2k, а не %ifarch %e2k -- т.е. только на v3, но не v4+.

Соответственно acc, например, падает вот так:

# acc
;;; note: source file /usr/sbin/acc
;;;       newer than compiled /root/.cache/guile/ccache/2.0-LE-8-2.0/usr/sbin/acc.go

Было исправлено ещё тогда же; непонятно, почему тогда же не ушло в сизиф,
но хоть сейчас отправил 2.7-alt2: http://git.altlinux.org/tasks/270886/
