bizzarre X fontspecs from xfstt

[David Morse <svref@yahoo.com>]

I apt-got xfstt in order to use bitstream-vera-sans-mono in emacs and 
xterm, however, now I get strange, broken behavior.  Running "xlsfonts" 
gets me, among other things:

-ttf-bitstream-vera-bitstream vera sans 
mono-medium-r-normal-roman-0-0-0-0-m-0-iso8859-1

This makes no sense for a number of reasons.  Its Family is not "vera" 
but "bitstream".  Its weight is not "bold" but "vera".  Its slant is not 
"italic" but "bitstream vera sans mono".  What!?  Type violations a 
plenty.  Applications like xterm refuse to use this font, typically 
saying they are "unable to open" it.
