Did you delete your native trackpad prefpane? I deleted the file from my dropbox because it is quite a large file (approx 100MB) and you can extract it for yourself from your Mavericks installer anyway (search the "Essentials.pkg" with the Pacifist.app). If you are really desperate and have lost your installer, let me know & I will re-up for a week or so (it takes a few hours to upload the damn thing!).
The native Trackpad.prefPane is a mere 3 MB after you remove the useless touchpad tutorial videos which reside in its Contents/Resources directory.
I have already uploaded it a few posts earier.
