4.2.2 w CLI and 4.0.6 w CGI on one Server

Hello, unfortunately I am forced to install 4.2.2 as an Apache-Module with the --enable-cli option and the CGI Version of 4.0.6 on one productive Server (I know, I know - it wasn´t my idea!). And I got to do it today :-(. I don´t think there will be any problems with the install itself, but there are some Issues I am worried about: - how can i make sure, that the two executables won´t overwrite each other? Will the --bindir do it for both compiles? - Both versions are currently installed as an Apache Module.

       - Do I _have_ to get rid of anything in the 4.0.6? (Is there a "make uninstall" for example?)
       - Will the (old) Apache Module of 4.0.6 get in the way of the (new) CGI version?

I´d appreciate any help or mentioning of issues I haven´t thought of. Thanks in advance, Patrick
