+This is an ugly usage solution for unixbench because it's not a friendly package software.
+
+So, what we do is to keep all files and rebuild locally.
+
+mkdir xxx/
+cp -r /opt/unixbench/src xxx/
+cp /opt/unixbench/Run xxx/
+cp /opt/unixbench/Makefile xxx/
+chmod +x xxx/Run
+mkdir xxx/pgms
+cp /opt/unixbench/pgms/* xxx/pgms/
+mkdir xxx/testdir
+mkdir xxx/tmp
+mkdir xxx/results
+cd xxx
+./Run
+
+do whatever you want.
