Надо бы почистить и пересобрать пакет gcc-common.
После пересборки появится циклическая зависимость gcc-common <-> gcc4.1.
Это циклическая зависимость правильная.

Если ты знаешь, что почистить, то почисть, пожалуйста.

Есть уверенность в том, что цикл будет разорван правильно?

Я удалил очень старые зависимости (до Master 2.4).

В gcc4.1.spec везде стоит PreReq:
$ grep -m9 -e -common gcc4.1.spec
PreReq: %alternatives_deps, gcc-common >= 1.4.7
PreReq: %alternatives_deps, gcc-common >= 1.4.7
PreReq: %alternatives_deps, gcc-c++-common >= 1.4.7
PreReq: %alternatives_deps, gcc-c++-common >= 1.4.7
PreReq: %alternatives_deps, gcc-c++-common >= 1.4.7
PreReq: %alternatives_deps, gcc-common >= 1.4.7
PreReq: gcc-common >= 1.4.7
PreReq: %alternatives_deps, gcc-common >= 1.4.7
PreReq: %alternatives_deps, gcc-common >= 1.4.7

Вот buildreq теперь будет путаться.
$ /usr/share/buildreqs/optimize_package_list gcc-c++-common gcc4.1-c++
tsort: -: input contains a loop:
tsort: gcc-c++-common
tsort: gcc4.1-c++
gcc-c++-common

Урро! Я реализовал разрыв циклов, типичных для -common пакетов,
в пользу не-common пакета.
