🚀 go-pugleaf

For a certain documents I prefer to use the Sans Serif font in place of the
default Times Roman. I have a style file which contains the following type
of command to re-define the standard fonts -

% sf.tex - auxiliary style file to use sans serif fonts in place of the cmr
% fonts. Several fonts have been comented out to save memory. Enable them if
% needed.

% ten point
 \font\tenrm  = cmss10              % roman -> sans serif
 \font\tenit  = cmssi10             % text italic -> italic sans serif
 \font\tensl  = cmssi10             % slanted -> italic sans serif
 \font\tenbf  = cmssbx10            % extended bold -> bold sans serif

% eleven point
 \font\elvrm  = cmss10    \@halfmag % roman -> sans serif
 \font\elvit  = cmssi10   \@halfmag % text italic -> italic sans serif
 \font\elvsl  = cmssi10   \@halfmag % slanted -> italic sans serif
 \font\elvbf  = cmssbx10  \@halfmag % exelvded bold -> bold sans serif

etc

That's fine for LaTeX but when I use xtex I get error messages such as -

Missing cmssbx10.173 ( -mag 333 -scaled 1728 cmssbx10 )
Missing cmssbx10.144 ( -mag 333 -scaled 1440 cmssbx10 )
Missing cmssbx10.120 ( -mag 333 -scaled 1200 cmssbx10 )
Missing cmssbx10.109 ( -mag 333 -scaled 1095 cmssbx10 )
Missing cmssi10.109 ( -mag 333 -scaled 1095 cmssi10 )
Missing cmssi10.100 ( -mag 333 -scaled 1000 cmssi10 )

and dvitops gives the following errors -

dvitops: warning: no exact font for cmssi10 at 328 dpi
dvitops: warning: no exact font for cmssbx10 at 328 dpi
dvitops: warning: no exact font for cmssbx10 at 360 dpi
dvitops: warning: no exact font for cmssbx10 at 518 dpi

Question how do I get hold of / build the font files that are missing?

Any pointers or hints would be most welcome.
