Solved... well, a workaround at least
Apparently, the program thinks that it is working from the root directory of the hard disk. As a workaround, try copying the config folder and the help files into the main / folder. When I get 10.9 I will try to solve the problem properly.

Running from the terminal is working as well =)

It does need the path into the package structure from the second reference you posted, using 'open R.U.B.E.app' will not work.

cd /Applications/rube-mac32-1.5.1
./R.U.B.E.app/Contents/MacOS/rube

Also as a heads-up, it looks like the workaround to copy the config folder to the root directory does not work under 10.9.

After doing so you get the following error when trying to start RUBE:
"You can’t open the application “R.U.B.E.app” because it may be damaged or incomplete."

I am guessing that 10.9 flags the app as possibly malicious as it is trying to read or write from the root directory.

Interestingly you still get that error on launch even after deleting the config folder from root. To fix that I had to rename the RUBE folder in /Applications and then launch RUBE again.

I don't know what i'm doing wrong
Even by starting rube from the terminal or move the help files and confic folder it's not working.

You should cd to the folder where the app, the config folder and rubehelp_en.* files are located together first. This makes the working directory the same as where the program is located:

cd <where your R.U.B.E.app is located>
./R.U.B.E.app/Contents/MacOS/rube

The solution I mentioned above (putting the config folder and help files in the root / folder) has not been checked by me. It was reported to me by one user that it worked. He was then running the program by double-clicking on it as normal.

I really don't know what to make of this, since that solution is working for some but not others. What a mess.

I put all files together into the root folder there is no different.
And by starting it by terminal you only can cd to: cd <where your R.U.B.E.app is located>
./R.U.B.E.app/Contents/MacOS
than I enter open rube right?
If this is right it's not working on my mac

I think in your case it would be:

Hi, I had this issue too. iforce2d's suggestion of:
is a workaround that works for me.

Hey
now I can open the program but there is now another bug/problem
I started rube by the terminal
I delete and download it again already but this is not the solution for this

Hi Hendrik
Could you describe a little more about what the problem is?
