Installation Problem when Configuring

[Matthew Pulis]

Hi,

I am trying to configure the installation of Mapserver, and this is the line I am 
using for configure :

yancho at Ubuntu:~/mapserver-5.0.0$ ./configure --with-postgis=/usr/lib/
postgresql/8.1/bin/pg_config --with-jpeg --with-xml2-config=/usr/bin/xml2-
config  --with-sos with-threads --with-httpd=/etc/apache2 --with-ogr=/usr/
bin/gdal-config --with-ogr=/usr/bin/gdal-config --with-wcs --with-wfsclient --
with-wmsclient --with-geos=/usr/bin/geos-config

and this is the error I am getting :

checking if GEOS support requested... yes
user supplied geos-config (/usr/bin/geos-config)
checking for GEOS version >= 2.2.2... no
configure: error: geos-config reports version 2.1.4, need at least 2.2.2 or 
configure --without-geos
yancho at Ubuntu:~/mapserver-5.0.0$


I tried to check on Ubuntu packages from where to upgrade geos-config but 
found nowhere .. any idea what I can do please?

Thanks beforehand :)
