Description:
------------
When installing 5.1.0-RC2-dev (snap) it says that PEAR was not installed and gives instructions to install.

What it doesnt say is that it installed mod_php into your apache directory, but didnt install the helper applications (and probably a few other things)

Reproduce code:
---------------
# cd php-5.0.5
...
# make install
...
# phpize -v

PHP Api Version:         20031224

# cd php5-200509211230
# ./configure && make && make install

Expected result:
----------------
The above shows that the php helper apps didnt get installed properly, which causes all sorts of hidden problems.

It says the installation process was incomplete, but part was completed.  Is this just a warning, or does it represent an error?  Surely it should just show a warning.
