estou tentando instalar o i3geo no ubuntu atravez desse tutorial:

http://www.softwarepublico.gov.br/dotlrn/clubs/i3geo/xowiki/instalacao fiz todas as modificações mais quando eu fui rodar o programa apareceu o seguinte erro: Warning: dl() [function.dl]: Unable to load dynamic library '/usr/lib/php5/20060613+lfs/php_mapscript.so' - /usr/lib/php5/20060613+lfs/php_mapscript.so: cannot open shared object file: No such file or directory in /var/www/i3geo/classesphp/carrega_ext.php on line 117 Warning: include_once(ms_configura.php) [function.include-once]: failed to open stream: Permission denied in /var/www/i3geo/ms_criamapa.php on line 115 Warning: include_once() [function.include]: Failed opening 'ms_configura.php' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/i3geo/ms_criamapa.php on line 115

alguem sabe como resolver isso?
