When compiling lirc-0.7.2 (as well as ebuild and "by hand" using the tarball from www.lirc.org) the following error blocks the use of lirc with a Hauppauge bt878 TV-card. I'm not quite sure what causes this error, but since lirc-0.7.2 builds flawlessly on other Linux distros, it's gotta be gentoo-related.

(In reply to comment #0) > /var/tmp/portage/lirc-0.7.0-r1/work/lirc-0.7.0/drivers/lirc_dev/lirc_dev.h:24, ^^^ That's definitely not 0.7.2. Anyway, neither of the versions currently in portage works with 2.6.14+ kernels... *** This bug has been marked as a duplicate of 111820 ***
