This is an optional package from IBM that you might not have on your system. You can grab the necessary files from the V1R2M2_base_4.7.2-files.tar.gz archive on the trac page (and follow the instructions re: how to adjust the bgclang wrapper script, etc. to make everything work). If you run into any problems, please let me know.
