+<p><b>Note:</b> For some native products (e.g. gcc, Python) the rules of version
+checking are not so strict as described in the table. Only major and minor numbers of version
+should coincide with prerequisite. Release number can be larger. It is done for making a possibility
+to use native products for newer versions of Red Hat (for example, Linux Red Hat 9 includes native
+gcc 3.2.2 installation).
+If native product has version number larger than that required by installation procedure,
+you will be prompted by the warning message like this: "You have newer version of gcc installed
+on your computer than that is required (3.2). Continue?". You can press "Yes" button
+to procede with the installation but in this case you should be aware of what you are doing.
+SALOME binaries (inluding other products) are compiled with the prerequisites from the list
+and most likely can not be run successfully if this products are not found.
+This can be only helpful if you intend to build all products from sources.</p>
