Comment(by jhpalmieri):

 Here's a new patch.  This deletes the initial doctests for have_dvipng
 (etc.); I think the remaining doctests still adequately test whether the
 functions are working, and should work in any order of execution.  For the
 doctest failures when latex is missing, I just changed the doctests like
 this:
 {{{
 -        sage: _run_latex_(file)
 +        sage: _run_latex_(file) # random - depends on whether latex is
 installed
 }}}
 and similarly for the {{{png}}} doctest.  Do you think that's good enough?
 It now passes all tests for me if latex and pdflatex are missing.
