Asterisk on a Synology NAS

I just installed Asterisk using ipkg on my sinology ds1010+ and i would like to install asterisk-gui so i can configure asterisk but i am getting the following error:

Package coreutils wants to install file /opt/man/man1/cat.1 But that file is already provided by package textutils

Would it also be possible to install
Asterisknow
or
Trixbox

on my Synology?
