If you do a manual build as mentioned below (not using the prebuilt rpm's) and use both php versions in CGI mode (not as apache modules) then it should be possible so long as the php4 is assigned to one directory and the php5 is assigned to another.

I am trying to explain that your output is one (PHP4 or PHP5). The question of running both in parallel seems to be difficult in this scenario. It also says when u will get to know that which version is now u running....

Not including the libraries and binaries in any paths might solve the problem and execution still could happen via a shell script for each to append the proper path before launch, but this is all just guessing.

If the parallel php5 could be installed from rpm also that would be great also.
