Does this look familiar?  Why would I be getting these errors when
following the Yocto Project Quick Start instructions, without changes?
 Did I miss something?

It does not. However this is when trying to build perl-native, i.e. Poky
is trying to build its own version of Perl but linked against your
system libraries etc and is unable to find some pthread functions to
link to.

Can you tell us which distribution/version combination you are using?

Could be that we need to patch perl-native to -lpthread ?

Is your host Ubuntu 11.04 on x86 (not x86_64)?  There was a patch for this
that I'm not sure got back ported into Bernard.

Oops.  I forgot to provide those details...

My host is Ubuntu 11.04 64 bit:

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=11.04
DISTRIB_CODENAME=natty
DISTRIB_DESCRIPTION="Ubuntu 11.04"
$ uname -m
x86_64

I ran `wget http://www.yoctoproject.org/downloads/poky/poky-bernard-5.0.tar.bz2`
(as directed in the Yocto Project Quick Start).  Does that 5.0
correspond to Yocto Project 1.0.1?

I found http://bit.ly/lzyY5b (an email on the gumstix-users mailing
list, archived on old.nabble.com), which appears to be the same
problem.  I ran:

$ sudo apt-get install pthread*
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'libpthread-stubs0' for regex 'pthread*'
Note, selecting 'libpthread-stubs0-dev' for regex 'pthread*'
libpthread-stubs0 is already the newest version.
libpthread-stubs0 set to manually installed.
libpthread-stubs0-dev is already the newest version.
libpthread-stubs0-dev set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I'll read through the rest of that thread to see if can find a
solution.  But I thought I'd send this information off in case it
triggers someone to suggest a solution specific to the Yocto Project.

The good news is that following the instructions in
https://wiki.yoctoproject.org/wiki/Working_Behind_a_Network_Proxy
seems to have solved my proxy problems.  But unfortunately I'm getting
errors after running `bitbake -k poky-image-sato`, following the
"Building an Image" instructions in the Yocto Project Quick Start.  (I
didn't make any changes to the conf/local.conf file generated by
`source poky-bernard-5.0/poky-init-build-env poky-5.0-build`, except
to add the CVS setup lines as directed in the
Working_Behind_a_Network_Proxy wiki page.)  When I repeat `bitbake -k
poky-image-sato` I believe I get the same results.

Here's the output, up to and including the first error:
