I used git to clone the source from https://github.com/WiringPi/WiringPi-Perl
and I was able to compile it with the build.sh (after updating it to point to the proper perl location) and that gave me a wiringpi.so. But I guess I'm not quite clear on the best way to use that. And then what I'm really wanting to do is use this wiringPi to communicate to a SPI based A2D chip I have hooked up. Anyone know what step to take next?
