Missmatch in wiki documentation

[JVGD]

In wiki page:
http://openbts.org/w/index.php?title=BuildInstallRun#Required_Libraries

It says:
You will also need to install liba53, which is included in the distribution. The following commands should install it correctly from the OPENBTS_ROOT

cd a53/trunk
sudo make install

And it should be:

cd liba53/
sudo make install

Further information:
Downloaded OpenBTS from source, switched to tag v4.0.0.
From the openbts root directory, I can see liba53 instead a53. There isn't any /trunk directory inside it either.

In the wiki reference of this repo, there is no documentation on this step.

I am not sure if this is version specific (maybe the directory was called a53 in later versions of OpenBTS) or maybe now there is no need to compile liba53 before building openBTS.

I am also not sure If this is the place for reporting the issue if it is not I would like you to point it to me so we can get this done.
