AFAIK DejaVa is a TrueType or OpenType font, configured via
fontconfig.  You need to have an XFT-enabled XEmacs.  To use
fontconfig-style fonts, you have to use set-face-font most likely.

    (set-face-font 'default "DejaVu Sans Mono-14.3")

xfontsel doesn't know about fontconfig.  Use fc-list to find out about
fontconfig fonts.
