So here it is. That was my first post so I did this.
I'm going to pass a link for you to download the necessary files. It is preferable you do this with vmware workstation/player/server or a PC-BSD 8.1 RC1 fresh installation. If forum moderators consider that this link is not appropiate, please feel free to contact me and if possible, give me a list of how can I transfer files through these forums:

The instructions are into the zip bundle you may download with the link above and are a little fuzzy so read carefully, these are in english and also in spanish language made into two different readmes. If you have any inconsistencies, doubts or problems with the zip file or some of the files inside, please contact me through here. Everything is malware free 
.
Here are some of the sites I've seen to make this possible:
Development Release: PC-BSD 8.1 RC1 (DistroWatch.com News) ---> to download the PC-BSD version I actually use, the BSD 8.1 RC1

Trouble shooting - Rxtx ---> really helpful
I hope this is helpful for someone who needs it or just for thinkering.
Regards.
