[Pacemaker] Building corosync from source on Angstrom

[Simon Platten]

Hi,
I have been struggling to build corosync in Angstrom Linux on a beaglebone
black which runs an ARM Cortex A8.  I have been using this page as a guide:

http://clusterlabs.org/wiki/SourceInstall

So far I've downloaded and built libqb, no problems there right through to
corosync.  I've managed to perform corosync up to the make, where I encounter:

gcc: error: @nss_CFLAGS@: No such file or director

If there is any further information required, please let me know and I will
do my best to provide it.  

Kind Regards,
Simon
