[mythtv-users] Fedora 15, mythtv 0.24-fixes compile cannot enable v4l and ivtv

[N. Voss]

./configure --enable-ivtv --enable-v4l | egrep "(v4l|ivtv)"

I have been compiling my own fixes branch on Fedora system since 2003. I 
recently upgraded to Fedora 15, because I was having other issues with 
my system. It was an upgrade so all of the same packages are there.

Now I cannot compile 0.24-fixes with v4l and ivtv enabled:

> ./configure --enable-ivtv --enable-v4l | egrep -i "(v4l|ivtv|video4)"
Video4Linux sup.          no
ivtv support              no

> rpm -qa | egrep -i "(v4l|ivtv|video4)" | sort
ivtv-firmware-20080701-21.noarch
ivtv-utils-1.4.0-10.fc15.x86_64
libv4l-0.8.3-2.fc15.x86_64
libv4l-devel-0.8.3-2.fc15.x86_64
xorg-x11-drv-v4l-0.2.0-12.fc15.x86_64

Any tips would be appreciated, since the configure script does not 
provide any feedback to what header file might be missing.
