__gnuplot_get_var__.m seems to fail while building documentation

[Thomas Treichl]

Hi,

I currently have the problem on MacOSX that I can't make the documentation right 
after compilation. The version that I tried to build is:

   $ hg tip
   changeset:   9110:22ae6b3411a7
   tag:         tip
   user:        David Bateman <dbateman at free.fr>
   date:        Sat Apr 11 16:26:01 2009 +0200

The error output is:

   makeinfo -I.. -I. -I./.. ./octave.texi
   ../../run-octave -f -q -H -p . --eval "sparseimages ('gplot', 'eps');"
   ans = [](0x0)
   error: __gnuplot_get_var__: stream to gnuplot not open
   error: called from:
   error:   /Users/Thomas/Development/octave/scripts/plot/__gnuplot_get_var__.m
   at line 47, column 5
   error:   /Users/Thomas/Development/octave/doc/interpreter/sparseimages.m at
   line 54, column 3
   error:   /Users/Thomas/Development/octave/doc/interpreter/sparseimages.m at
   line 30, column 2
   make[3]: *** [gplot.eps] Error 1
   make[2]: *** [interpreter] Error 2
   make[1]: *** [doc] Error 2
   make: *** [all] Error 2

I then had a look at __gnuplot_get_var__.m line 40 and removed the semicolon of 
this line: ostream always seems to be an empty matrix. Nect I put a "get (h)" 
right before line 40 and found out that there is no __plot_stream__ option 
available in the return value of "get (h)". Any ideas?

Thanks,

   Thomas
