Here's what the linker is returning - I *think* that should tell us
without tracing.

[-][~]:: ldconfig -p | grep libgbm
libgbm.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgbm.so.1
libgbm.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libgbm.so

So, correct you are. It's showing the libs only in the standard
packaged X location.

Doing a find for the libs in /opt, which is where I'm putting stuff:

[-][~]:: find /opt/ -type f -name "*libgbm*"
/opt/xorg-orig/lib/libgbm.so.1.0.0
/opt/xorg-orig/lib/libgbm.la

...and they're found /only/ in the first build of xorg I did a month or
more ago, which I've since renamed to xorg-orig.

The xorg I'm running now is rooted in /opt/xorg-new, which does not have
these libs at all. What switch am I missing that is not getting them
built? Does a different module in modules-file need a parameter to
build gbm? I do have --enable-gbm set for mesa/mesa, so I'm confused as
to why they are not getting built. mesa/mesa/config.log has
HAVE_GBM_FALSE='' and HAVE_GBM_TRUE='#' set.

I've attached that config.log as well for your perusal if it might be
helpful.

Thanks again for assisting,
-C
