in TM2 ->preferences->Bundles
uncheck the LaTex Bundle

created the Bundles dir
mkdir ~/Library/Application\ Support/TextMate/Bundles
cd ~/Library/Application\ Support/TextMate/Bundles

then
git clone https://github.com/dhowden/latex.tmbundle.git

is that right? if so what should i do now?

Ok, bundles installed manually in TM2 should go in:

~/Library/Application\ Support/Avian/Bundles (see here http://blog.macromates.com/2011/locating-bundles/).

... so this might be your problem at the moment. Once this is done, you should be able to see the LaTeX bundle in the bundle editor of TM2.
