Thanks for people who tested and gave some clues about this port, I've forgotten about some "obvious" dependencies as I alread had them when compiling manually ion-devel.
I quickly worked out this new version and if everything goes well, will submit it to a maintainer or try other official way to the ports's tree. Notice that I preferred using freebsd X Prefix path (/usr/X11R6) instead of /usr/local like all ports mainly used for X. Anthony.
