That symbol is in libpthread.so which we should already be linking
against because we already use many pthread symbols. Can you provide
the output of
$ ldd src/.libs/libvirt.so.0
# ldd src/.libs/libvirt.so.0
linux-gate.so.1 => (0xb7f4b000)
libxml2.so.2 => /usr/lib/libxml2.so.2 (0xb7da0000)
libgnutls.so.13 => /usr/lib/libgnutls.so.13 (0xb7d2a000)
libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0xb7d12000)
libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7bc3000)
libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb7bbf000)
libz.so.1 => /usr/lib/libz.so.1 (0xb7baa000)

And what OS distribution, version and CPU architecture are you using ?
It is Ubuntu 8.04, on x86.
Do you have any idea?
Thanks,
