Fix "usr/bin/Xvnc: undefined symbol: pixman_composite_trapezoids"

This is one another error which appears while trying to restart vncserver services which came to me in CentOS 6.2.

Error:
/usr/bin/Xvnc: symbol lookup error: /usr/bin/Xvnc: undefined symbol: pixman_composite_trapezoids

/usr/bin/Xvnc: symbol lookup error: /usr/bin/Xvnc: undefined symbol: pixman_composite_trapezoids
Solution:
Make sure that the below mentioned package is installed and updated to the latest version available.

# rpm -qa | grep pixman
pixman-0.26.2-5.el6_4.i686
pixman-devel-0.26.2-5.el6_4.i686

If the above packages are missing, install them using yum

# yum install pixman pixman-devel

Now try starting your vncserver services and let me know your success and failure rate.
