Bugzilla Bug 26987

Building doxygen with USE flag 'doc' requires ghostscript (and tetex?) to
create the documentation 
successfully. I have tetex on my system, but not ghostscript and doxygen's
`make doc' fails.

Shouldn't ghostscript be in doxygen's dependancies with USE='doc'?

(On my newly installed system I have already installed tetex. So that step went
ok, but shouldn't tetex 
be a dependancy as well?)

Reproducible: Didn't try
Steps to Reproduce:
On a system without ghostscript do `USE="doc" emerge doxygen'

Actual Results:  
sh: line 1: gs: command not found
Problem running ghostscript. Check your installation!

Tetex is already a dependency. Adding ghostscript to DEPEND/RDEPEND for 1.3.3
