I already told you what to do, I can't be any more explicit than this:
Code:
$ rm -rf /usr/src/linux*
$ emerge gentoo-sources
$ cd /usr/src/linux
$ make menuconfig
... and then follow from there. If you don't have a clue on what the hell I am talking about, then I really wonder how did get up to this point at all...
If you are truly interested in installing Gentoo, the first thing you should do is to use the real handbook, and not the quick install guide. That one is aimed only at experienced users who just need some pointers to aid their memory in the installation process.
I can't guide you through the whole process, all I can do is to point you to the correct hand book for your architecture, which would be this one for x86_64/amd64 (64 bits):
http://www.gentoo.org/doc/es/handboo...book-amd64.xml
Or this, for x86 (32 bits):
http://www.gentoo.org/doc/es/handbook/handbook-x86.xml
Everything is detailed in there and I am not going to replicate the manual here. You should start over from scratch, and this time follow the real manual and do as it says. If punctual problems or questions arise, or you don't understand something in that manual or the like, I will be more than happy to help with anything, but that's all I can do. I can't really install Gentoo for you.
If you feel that that manual is too long for you to read and follow, then you should really be picking something else. Gentoo is not that difficult, but you need to be ready to work and learn. If you are not interested in that you probably made the wrong choice.
