Shit happens. But thanks for your help. :)
I'm gonna ping you on IRC.

Ok, I'll correct that.

Using OpenRC makes rcorder useless: it's used in /etc/rc script.

I didn't know that, and it's great if "g" suffix is added. 
But Portage needs some GNU tools like GNU sed: some scripts/patches 
don't work if you don't use it. Same thing about awk:
I read ebuild.sh source code and "gawk" command is used. I'll correct this but
I'll still install them in my stage.

On my "correct" list.

Yes, NetBSD has also his own version of uuidgen and libuuid. On my list.

which means: we should talk about this on IRC. I'll give you errors logs. It's
mainly compilation errors.

I'm gonna rename it.

NetBSD devs seem to have patched GCC sources to suit to NetBSD. I maybe writing
a big mistake. But I have tried every GCC's ebuilds and none of them have
worked. Even by downloading GCC sources on gcc.gnu.org website, ./configure and
make, it simply doesn't work. That's why I've created an ebuild..

Yes, it should work. In fact, it's because I haven't yes packaged my ebuilds
that I've used patches. To compile and install one of my ebuilds, you'll need
to download sources via CVS. My ebuilds are just a frontend to /usr/src. I know
it's not the right way to do: Davide seemed to be fine with that, but Luca
explained me how to proceed. For the moment, I'll stay with this configuration
because it "works". But, of course, I'll correct this after GSoC.

I've tried to compile Kerberos 5 1.7 this morning and it works without changing
any ./configure flags. The only error comes from PKINIT: it is an extension
to Kerberos that adds public key cryptography. Do we really need it ?
Thus, if I remove it from Makefile, compilation works fine.

Yes. The problem comes from "passwd" program which segfaults. I need to dig on
this more. I can provide a .core if you want.

Anyway, thanks again for your help. :)

Cheers!
