After following through the list of items, I was disappointed with the quality of the solutions available on Linux.
I discovered through more digging on the net that konquorer had built in some very nice subversion integrations several years ago and I'm quite impressed with the quality.
Note that konqueror requires kde, kdesvn and kompare.
The solution still no where near TortoiseSVN for windows but its still very useful for many usecases and a relief for us Windows to *nix desktop converts.
My current distribution is OpenSuse 13 with KDE.
