No offense but you've had four actively running threads in this forum in the last week, three of which (including this one) have had responses along the lines of "stop using old versions of software". Mint 11, how do you still even have a copy of that? It's four years old and it's been marked obsolete for nearly three years.
To answer your question, a quick gander through, the link looks about right. However, it's ridiculous to run such an old version. Whether your version of Mint works "properly" or not with the latest version of GNOME is unknown.
If you just want bog standard GNOME, I'd just install Debian and be done with it.
