actually,  I can confirm now that gs AFPL 8.53 is the "culprit" here on #2,
copied below again (though it is not a bug but a feature, albeit one you
need to know about.)  the -dSAFER switch, which appears in later versions of
AFPL gs, not only eliminates renamefile and deletefile (manpage), but
seemingly also allows only fonts in the GS_LIB path to be used
  export GS_LIB=/usr/local/share/texmf/fonts/type1/yandy:$GS_LIB
fixes this protection problem for me.    hope this will help some of you
when you run R pdf files through gs.    regards,
