This suggestion definitely helped. Now, luaootfload-tool successfully 
rebuilds the FNDB.  So, definitely a step in the right direction. My MWE 
(below) compiles, more or less. Turns out something is balking on 
unicode-math.  If I try to compile the MWE as is, I get the following error:

))(load luc: 
$TEXMFCACHE/luatex-cache/generic/fonts/otf/xits-math.luc)(load luc:
! Undefined control sequence.
\um_set_mathcode:nnn #1#2#3^^@-\Umathcode
                                         \int_eval:n {#1}=\mathchar at type 
l.6 \setmathfont{XITS Math}


Basically, it chokes on unicode-math.


\setmathfont{XITS Math}
