OK, changing to "\setmathfont{TG Pagella Math}" fixed the problem. Thanks.

But now I'm confused, given thatI do have the several texgyrepagella-xxxxl.otf text fonts and texgyrepagellamath-regular.otf in /usr/local/texlive/2012/texmf-dist/fonts/opentype/public/tex-gyre and /usr/.../tex-gyre-math folders, respectively.

(1) Why then does my indicated declaration for \setmainfont work with actual file names?

(2) Why didn't the file-name work for texgyrepagella-math.otf when that file was in texmf-dist?
