Just sticking this here for the rest of the Internet to benefit from.
I was rebuilding the HTPC with an updated OS and needed to get LIRC working again for my remote using the original XBox DVD dongle connected via USB.
I found this post which describes the process of building and using the lirc_xbox kernel module. Which worked fine in XBMCBuntu (based on Ubuntu 11.10). But when I tried to follow the instruction in Linux Mint 13 XFCE I got the error "E: Unable to find a source package for lirc" when attempting the line "sudo apt-get build-dep lirc".
I worked around the problem by running the same command on my laptop running Ubuntu 12.04 which gave me the correct list of dependencies:
autotools-dev build-essential debhelper devscripts dh-apparmor diffstat dpkg-dev g++ g++-4.6 gettext html2text intltool-debian libasound2-dev libdpkg-perl libftdi-dev libftdi1 libgettextpo0 libice-dev libirman-dev libjack-dev libjack0 libportaudiocpp0 libpthread-stubs0 libpthread-stubs0-dev libsm-dev libstdc++6-4.6-dev libunistring0 libusb-dev libx11-dev libxau-dev libxcb1-dev libxdmcp-dev libxt-dev patch po-debconf portaudio19-dev quilt x11proto-core-dev x11proto-input-dev x11proto-kb-dev xorg-sgml-doctools xtrans-dev
I used that list in a "sudo apt-get install [long list of package names]" and was able to successfully get the build dependencies installed and follow the rest of Mr. Plow's instructions and get my remote working properly.
Since I saw that a few other people were having the same issue, I thought I'd post this in case anyone else gets stuck on the problem.
