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.
