[mythtv-users] Mythtv 31 won't configure/compile error in Debian 10

[Mark]

Getting a new install going on Debian 10 / Stable.

Following the source install instructions like i have always.

Installed the full list of dependencies.  No issues there.

Get to the ./configure step.  It goes off in the background, presumably 
testing for my dependencies.

Comes back with ERROR:  can not find libbluray.

I did install the bluray library.  I double checked.  Still says the 
same thing.

I checked config.ep, all the way at the end, i find it exits with the 
above error, but it's failing on

udev_new call.  udev-dev is installed.  Where do i look for the problem 
here?

Here's the relevant chunk of config.ep:
