dvipdfmx; fontmapsx is missing

[Brendon Higgins <blhiggins@gmail.com>]

Hi list,

I'm trying to figure out why some text in an included EPS figure was being 
omitted in a PDF that was being generated from a DVI using dvipdfmx. I'm not 
sure if this is the reason or not, but I noticed dvipdfmx warning that it 
couldn't find fontmapsx. strace tells me it's looking in sensible places 
(/etc/texmf/dvipdfm/fontmapsx and /etc/texmf/dvipdfm/config/fontmapsx), but 
the file really doesn't seem to exist anywhere on my system. 'locate 
fontmapsx' turns up nothing. 'dpkg -S fontmapsx' can't find any installed 
package that should own fontmapsx.

I'm lost. Where is this file supposed to have come from?

Peace,
Brendon
