The "warning" at the end of make install is accurate and informative.
1) It's tells you that PHP is using it's own built-in, native MySQL support. How much more clearly do you want it stated? "You can connect to MySQL now"?. As a brief read of the docs would have told you, MySQL support is built into PHP, and has been so since 4.0.0 RC1. No additional config options or external modules are needed. I'd also disagree with your statement that PHP is "pretty much usless" with MySQL support. Look at the function guide..... PHP does lots of over things and talks to lots of other databases thank you very much.
2) It tells you that you can't use any external MySQL modules or libs with your new PHP build. Amazingly enough, they'd conflict with the native ones that PHP is compiled to use. For a normal installation, you don't need to use the --with-mysql config option. You only need that option you want to use non-standard or customized MySQL lib's in the make. Have you hacked yourself a truely custom copy of MySQL? No? Don't worry about it.
Just a subtle hint... based on what I've seen from your last couple posts here. You'll get more help, and have a generally better experience, if you don't always sound like someone just finished pissing in your cornflakes. We're pretty laid back here, but we don't need to waste our time reading posts that are always shitting on everything and placing the blame for your inablity to compile PHP and/or read the manual (which is where all the answers are) on the language/documentation authors instead of where it belongs.
We've all experienced problems in the past and been frustrated with something that just won't work. However, we haven't vented those frustrations in a pretty immature manner on a public forum. Instead we politely ask if anyone knows the answer to our problem. Someone usually knows the answer and shares their knowledge/experience. Problem solved. Ask in a pissed off manner and help magically becomes somewhat less forth coming. Is there a lesson here perhaps?
