GEOS not found

Hi,

I've installed GEOS following these steps:

[root@15900696 ~]# cd /usr/share
[root@15900696 share]# wget http://download.osgeo.org/geos/geos-3.3.2.tar.bz2
[root@15900696 share]# tar -xvjf geos-3.3.2.tar.bz2
[root@15900696 share]# cd geos-3.3.2
[root@15900696 geos-3.3.2]# ./configure && make clean && make
[root@15900696 geos-3.3.2]# make install
[root@15900696 geos-3.3.2]# ldconfig
[root@15900696 geos-3.3.2]# vi /etc/ld.so.conf

Added the line:
/usr/local/lib

Saved (ESC -> :x) 
Run ldconfig
[root@15900696 geos-3.3.2]# /sbin/ldconfig

Then I've checked it's properly installed:

[root@s15900696 ~]# geos-config --version
3.3.2

Then I've installed GeoPHP 7.x-1.4. In the status report I get the message:

GeoPHP library installed and OK. However, GEOS is was not found. While not required, you will see performance improvements if you install the GEOS PHP extension. See the following link for more information.https://github.com/phayes/geoPHP/wiki/GEOS

It seems that GeoPHP doesn't find the location of GEOS.

Any idea about how to solve this problem?

Thanks!
