The good news is that following the instructions in

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:

And here's the head of log.do_compile.27994:

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.
Gary, you are spot on. Looks like the patch *did* make it into the
Bernard point release (5.0.1) too!
