Strange thing that it wants an older version than the one you have installed..! If I were you, I'd rather not downgrade. Try downloading the latest source here
and compiling it yourself. If for some reason that won't work for you, try the latest stable version
. However I really suggest you try to get the beta version working as it has some new features and for me it's not at all unstable.
If you have trouble compiling, do a ./configure --help to see what options you can give to the configure program and read the README and INSTALL files. If you are still having trouble then, I'll be glad to try and assist you.
Make sure to post any errors you are getting in that case!
