[gentoo-user] emerge gives backtrace during first-time install of gentoo in a Debian sarge chroot.

[Hendrik Boom]

Installing gentoo for the first time, starting yesterday.  I just got to
the point of choosing the system logger as described in section 9b of
   http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=9
and syslog-ng gives me a traceback.

That was from the second time I issued the command.  The first time I got about
487 lines of output, ending with:

Context:

I'm installing this using a chroot from a Debian sarge system. 
I've encountered a few anomalies along the way, but I suspect most of them
are cosmetic, and that some just need a documentation update.
I don't think they are related to the tracebacks, but I mention them below
just in case they are a clue to the deeper problem.

(1) The portage file on the mirror was called
  portage-latest.tar.bz2.tar
instead of
  portage-latest.tar.bz2

(2) Of course, from sarge I couldn't run mirrorselect.  So I picked a
mirror by hand, and it seemed to work.

(3) At section 7.d, where I was supposed to
  zcat /proc/config.gz
there was no such file.  But the file I was supposed to create,
  /usr/share/genkernel/x86/kernel-config-26
already existed, so I just used the one that was already there.

This may have resulted from the fact that /proc was, of course, a window
into the Debian 2.6.8 kernel instead of the 2.6.17 installer kernel.

(4)  When doing
  genkernel all
I got the message
  mount: special device /dev/BOOT does not exist
  * warning: failed to mount /boot

There was still a directory /boot on the intended partition into which I
was installing gentoo, so I presumed it would use that one for /boot, as I
intended, and just let it go on.

(5) I found the installation of locales and keymaps.  None of the available
locales had "UTF-8" in their names, even though some of the suggested ones
did.  Should I presume that the UTF-8 adaptation is created by the locale
generating software?  What I want is a system that uses UTF-8 internally
and keyboards and consoles that accept input in several languages --
English, French, math, Japanese, and mathematics.  I guesses some entries
and went on -- confident that this can be fixed after installation.

What further information should I dig out to help track down the
problem?
