Автоматически пока никак.  В текст робота вставить не могу -- итак еле
удается оставаться в пределах 50К (лимит письма в рассылку).

Полуавтоматически (то есть вручную) -- сравнить совпадающие символы в
/usr/lib/liballeg-4.2.0.so и /usr/games/atanks.  Делается это примерно
так:

$ cd `mktemp -dt`
$ rpm2cpio $sisyphus/files/i586/RPMS/liballegro-4.2.0-alt1.i586.rpm |cpio -idm --quiet
$ rpm2cpio $sisyphus/files/i586/RPMS/atanks-1.1.0-alt2.i586.rpm |cpio -idm --quiet
$ nm -D ./usr/lib/liballeg-4.2.0.so |awk 'NF==3{print$NF}' |sort -u >1 
$ nm -D ./usr/games/atanks |awk 'NF==3{print$NF}' |sort -u >2
$ comm -12 1 2
