I've compiled apache with php_suexec support.

Well, then I realized that when I run php in the shell it shows be the old version instead.

I've find that there are three places where php could be located:
1) /usr/local/bin/php
2) /usr/bin/php
3) /usr/local/cpanel/3rdparty/bin/php

1st seems useless... how to avoid of it? Or I will be in need of reinstalling php there as well?..

2nd is used by apache with php_suexec (at least the php used there has /usr prefix).
This php was compiled by makecpphp which was adjusted to have own configure options and /usr prefix.

3rd is used by apache for cPanel php (!!) E.g. when I run Horde I got another version of php!

So I'm a little confused... I've had installed php with /usr/local/cpanel/3rdparty prefix as well just for cPanel to use it for webmails!

Conclusion:
we was insisted to install php in /usr for our customers to use latest php and do the same for /usr/local/cpanel/3rdparty for cPanel itself.

Could anyone explain it? (too many php places IN USE are there...)
