I'd rather not have my old libphp#.so file over-written when I install a new version, in case things go horribly wrong and I want to just roll-back...
Then you have the same reason to worry right now - every php5 install from 5.0.0 to 5.2.3 overwrites libphp5.so.
There was a time where one could have 2 php mod versions running at once, as I recall, and having different filenames was kinda important, eh?
Well, there was a setting that kinda allowed that, but I'm not sure it ever worked correctly - there are all sorts of symbol clashes, etc.
On the other hand, you can happily run two (or a dozen :) PHP versions right now - just install any FastCGI implementation, compile two cgi-fcgi PHPs and install. Only thing you would need to care about is to give them separate php.ini's and/or separate extension directories.
