I've tried this, removing just the math-fonts, then all the CM + LaTeX  
PostScript fonts,
then the screen suitcases as well, ...

But nothing works.
I have *not* logged-out, or restarted, in case there is some caching.

Your explanation of relating my problem to Textures' fonts is  
interesting,
as it might also apply at 10pt size, yet that works fine.

A possible explanation is that a complete set of 10pt .tfm
files are compiled into the format.

Yet with  -kpathsea-debug=-1  tracing, at 12pt  some .tfm files are  
read:

kdebug:fopen(/usr/local/teTeX/share/texmf/fonts/tfm/public/cm/ 
cmr12.tfm, rb) => 0xa0009978
kdebug:fopen(/usr/local/teTeX/share/texmf/fonts/tfm/public/cm/cmr8.tfm,  
rb) => 0xa0009920
kdebug:fopen(/usr/local/teTeX/share/texmf/fonts/tfm/public/cm/cmr6.tfm,  
rb) => 0xa0009920
kdebug:fopen(/usr/local/teTeX/share/texmf/fonts/tfm/public/cm/ 
cmmi12.tfm, rb) => 0xa0009920
kdebug:fopen(/usr/local/teTeX/share/texmf/fonts/tfm/public/cm/ 
cmmi8.tfm, rb) => 0xa0009920
kdebug:fopen(/usr/local/teTeX/share/texmf/fonts/tfm/public/cm/ 
cmmi6.tfm, rb) => 0xa0009920
kdebug:fopen(/usr/local/teTeX/share/texmf/fonts/tfm/public/cm/ 
cmsy8.tfm, rb) => 0xa0009920
kdebug:fopen(/usr/local/teTeX/share/texmf/fonts/tfm/public/cm/ 
cmsy6.tfm, rb) => 0xa0009920

Why no  cmsy12 ?
There isn't one!  It's normally scaled from  cmsy10 :

</usr/local/teTeX/share/texmf/fonts/type1/bluesky/cm/cmr12.pfb>
</usr/local/teTeX/share/texmf/fonts/type1/bluesky/cm/cmsy10.pfb>
</usr/local/teTeX/share/texmf/fonts/type1/bluesky/cm/cmmi12.pfb>
Output written on xtest.pdf (1 page, 8286 bytes).
    (using pdfLaTeX)



However, removing the Textures' fonts *does* force  xdv2pdf  to find
the  .otf  ones, as you claimed in an earlier email.

viz. for 10pt:

[GlenLivet:~/Documents/tests] rossmoor% xdv2pdf -v xtest.xdv
[1
{fontmap: /usr/local/teTeX/share/texmf-var/dvips/config/psfonts.map}
{activated:  
/usr/local/teTeX/share/texmf-local/fonts/otf/bluesky/cm/cmmi10.otf}
{activated:  
/usr/local/teTeX/share/texmf-local/fonts/otf/bluesky/cm/cmsy10.otf}
{activated:  
/usr/local/teTeX/share/texmf-local/fonts/otf/bluesky/cm/cmr10.otf} ]


but for 12pt:
[GlenLivet:~/Documents/tests] rossmoor% xdv2pdf -v xtest.xdv
[1
{fontmap: /usr/local/teTeX/share/texmf-var/dvips/config/psfonts.map}
{activated:  
/usr/local/teTeX/share/texmf-local/fonts/otf/bluesky/cm/cmr12.otf} ]

  ... which shows that math-fonts are missing.



Here is a bit more evidence:

[GlenLivet:~/Documents/tests] rossmoor% grep cmsy10 xtest.log | grep 12  
| grep font
reserved at f ->extract at rangefontinfo  
<10.95><12><14.4><17.28><20.74><24.88>cmsy10
reserved at f ->extract at rangefontinfo  
<12><14.4><17.28><20.74><24.88>cmsy10<-*>@ni
external at font ->cmsy10 at12.0pt
{select font cmsy10 at 12.0pt}
{retaining OMS/cmsy/m/n/12=select font cmsy10 at 12.0pt}

external at font ->cmsy10 at12.0pt
                        ^^^^
    could the lack of a space here have any effect ?

  I'd thought that this was the priority --- evidently I was mistaken.

  #3. sounds like a good idea, though perhaps it is impractical...

#4 sounds even better:

    + existing .tfm files cannot have spaces in the name;
    + the scheme I proposed earlier for LaTeX files was
      built with  "...." assumed.

Let me test it when it's ready.
Hopefully then my 11pt and 12pt problems will just go away.
