Log Message:
Make sure to install the _CLI_ version to ${PREFIX}/bin/php, and _CGI_
to ${PREFIX}/libexec/cgi-bin; install also couple more files same way
as PHP4

Of particular note is that CLI ignores setting of register_argc_argv
(treats as if it would be On), so it's no longer necessary to do anything
special for Pear packages to work. g/c MESSAGE warning about the Pear issue.
