Hi Toni,
After some adventures with getting scons configured, I no longer get
errors concerning LIRC. I actually installed LIRC before playing with
scons, but that didn't help. Once I ran a scons build the LIRC errors
vanished. The next set of errors regards ALSA (which is definitely
installed: alsa-lib-1.0.9rc4), so hopefully someone else will have
something to contribute:
