Before I am flogged for my ignorance, I confess this is my first iteration of freenas installation. Currently using 9.10.2 Stable. I have installed a Chelsio T520-SO-CR ethernet card. The bios recognizes the card, however freenas doesn't recognize it. I know you have to download the driver which was done. Copied the contents of kernel-head to /usr/src. According to the manual, I have to compile freebsd. This fails when trying to issue the command make buildworld. The error states it can't find a compiler. Now, obviously I am lost, but it seems weird that I have to compile the entirety of freebsd in order to install a driver. I could really use some guidance. I have the manual for the card, however the actual instructions haven't worked. Any help is appreciated.
