A month or two ago, I proposed eliminating the ability to use Apple's Apache and only use MacPorts's Apache. Several people objected to this, which is why I proposed the compromise in which both are available.
Some reasons to prefer Apple's are that it gets auto-upgraded by Software Update, and that you can control it from System Preferences
Sharing > Personal Web Sharing. With the MacPorts version, you have to use the terminal for both tasks, something some users are not comfortable with.
Now I understand the situation, Thank you. But still I can't use php5 MacPorts' apache... Could you please tell me the way to use MacPorts' apache with php5 without manually editing php5's portfile? I tried: $ port install php5 +mysql5 # failed. seems variant macosx is implicitly used.(my variants.conf is empty) #so I tried the next. $ port install php5 -macosx +mysql5 configure: error: This c-client library is built with Kerberos support. Add --with-kerberos to your configure line. Check config.log for details. Error: Status 1 encountered during processing. I didn't try but I think if I'd use +apache2 because variant apache2 don't have "if { ! [variant_isset macosx] }" on the portfile.
