Bugzilla Bug 50423

The LyX ebuild depends on 
	app-text/xpdf
	app-text/gv
But it doesn't actually need these programs.  They are viewers, and any old 
ps/pdf viewers will do in their place.  In fact, no viewer is really REQUIRED
to use LyX.  There are lots of viewers/translators for various file formats
that are not listed as LyX requirements.  For example,The default viewer for
html is mozilla, but mozilla is not required to use LyX - any html browser will
do (or no browser at all, if you don't plan to make html files).  I think the
above requirements should be removed, or replaced with virtual/pdfviewer,
virtual/psviewer or something like that.  

Reproducible: Always
Steps to Reproduce:
1. emerge lyx

Actual Results:  
gv and xpdf are merged, then lyx 

Expected Results:  
only lyx should be merged

printing herd: any thoughts about it? I personally think such virtuals
are useful. For example, lyx detects acroread, gv, ghostview and xpdf
for PDF previewer, and gv and ghostview for PS previewer. (We may add
app-text/gpdf to virtual/pdfviewer, and app-text/pspresent and
app-text/ggv to virtual/psviewer)

i like the idea.

even more worse !
emerge xpdf installs openmotif which (for me) is an expansive build. But strange - a qpkg -q openmotif shows neither one program in need ! Also equery depgraph xpdf - nothing !! But emerge xpdf => 1.[N openmotif-x.y.z] !!!
On the other hand . who is running lyx does usually have a runnig X. And there are a lot more dependencies for that. Also strange - qpkg -q gv on my system does not show one programm i have installed (lyx of course - but gv was there before). But it was installed as dependency of anything. Bugs ???
I would agree in putting both of them into a virtual requirement.

so we just need someone to do the work ;D

I'll do this then ;-)

Fixed in CVS.
