Maybe not a lot of help...
When I emerge MythTV, it looks in the /usr/include directory.
However, if you are using dvb support from the kernel, then the
includes are in (assuming you compile in /usr/src)
I had to manually edit the ebuild to show that location instead of the
default /usr/include. Also, you will have to recompile (re-emerge)
mythtv with USE="dvb" as one of your USE flags (either at the command
line or in make.conf).
