два вопроса

Добрый день.У меня возникло два вопроса.После переустановки gentoo я никак не могу поставить пакеты virtualbox и nvidia-drivers.Выдается следующее:
localhost z # emerge virtualbox

И второй вопрос.При запуске некоторых приложений(в частности Metatrader4) под wine выдается следующая ошибка:

wine ./terminal.exe
fixme:debugstr:CheckRemoteDebuggerPresent (0xffffffff)->(0xbaab69): Stub!
err:seh:setup_exception_record stack overflow 888 bytes in thread 0009 eip 7ef97b57 esp 00230fb8 stack 0x230000-0x231000-0x330000
Я просто никак не пойму где искать ошибки.Я новичек в gentoo. До переустановки все работало нормально.Систему я переустановил по той же системе что и до ӕтого.Единственное, что я выбрал другой stage.До ӕтого был -686, а сейчас х86.Ядро 2.6.25-r6.Большое спасибо
