Illegal instruction, VIA_Nehemiah

[Maciej Świniarski]

Witam,
kilka dni temu zainstalowałem świeże TH na nie standardowej maszynce,
niestety nie wszystko jest ok i nie bardzo mam pomysła za co się łapać,
może ktoś ma jakąś sugestię?

Zaraz po instalacja wylukałem ze `less` oraz `host host.pl` wywalają
się wypisując
"Illegal instruction"
kilka dni później zrobiłem update gdzie był nowy less i nowe bind-utils
no i zaczelo działać :) ..jednak nie wszystko do dziś nie działa mi
perl oraz apache. Oto co zdołalem z nich wydusić.

Wydaje mi się interesujące ze strace zazwyczaj kończy się na uname()
..dodaj ze ze starszymi jajkami dzieje się to samo
