Linuxstok

Instalei o linuxstok, quando tento inicializar via terminal dá o seguinte erro: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/php-gtk2/lib/php/extensions/no-debug-non-zts-20060613/mcrypt.so' - libltdl.so.3: cannot open shared object file: No such file or directory in Unknown on line 0

php-gtk2: symbol lookup error: /usr/lib/libpangocairo-1.0.so.0: undefined symbol: cairo_scaled_font_get_font_options

Alguém sabe como resolvê-lo?
