I'm trying to send the next post to:
"Frank Denis \(Jedi/Sector One\)" j@xxxxxxxxxxxx


But  my email provider doesn't let me to send this message to: j@xxxxxxxxxxxx
It's about a bug.
-------------------
Hello Frank,
I supose that I should write to you directly, or am I wrong? Besides, I'm Spanish, so please sorry my english.
The 2.6.11-rc1-mm1-jedi1 keeps on failing. Disclaimer : I'm a newbie. This is the first time I patch something. And this friday was my first contact with Gentoo, ebuilds, emerge and all those things  (I came from Mandrake 10.1 because I feel that there was something working bad).


What I have done (is it OK?):
tar -xvjpf linux-2.6.11-rc1
bzip2 -dc 2.6.11-rc1-mm1.bz2 | patch -p1
bzip2 -dc 2.6.11-rc1-mm1-jedi1.batch.z2 | patch -p1


Everything works fine, but when I do "emerge eagle-usb":
