gnuplot tikz terminal - gnuplot

Question

How do I enable the tikz terminal in gnuplot on Mac Os X(10.6.8)?
I have latex with working tikz. Now I installed lua from http://www.lua.org/ and Downloaded gnuplot4.4.4, unpacked it, and run
$ ./configure
$ sudo make
$ sudo make install
Now I can set the tikz terminal, but there are still problems
gnuplot> set terminal tikz
Terminal type set to 'tikz'
Options are 'color dashed'
gnuplot> plot sin(x)
\begin{tikzpicture}[gnuplot]
/usr/local/share/gnuplot/4.4/lua/gnuplot-tikz.lua:252: bad argument #7 to 'format' (string expected, got no value)
stack
gnuplot>
I have also tried to install homebrew from https://github.com/mxcl/homebrew/wiki/installation although I did not do the Java Developer Update - is that necessary?
Now 'brew install gnuplot' gives problems with the glib dependency
hpek#melda:~$ brew install glib

When I install gnuplot manually, am I suppose to know about and install all these dependencies myself?

Answer 1

The problem is that the 252 (or 254 in my version) of the LUA script is using a format command with less argument than necessary. Adding a "X" as #5 argument (a.k.a. script revision number) solves this.
Here is my new code in the script:
gp.write(string.format("%%%% generated with GNUPLOT %sp%s (%s; terminal rev. %s, script rev. %s)\n%%%% %s\n",
term.gp_version, term.gp_patchlevel,
string.sub(term.lua_term_revision,7,-3),"x",
pgf.REVISION,os.date()))
I guess there is better to do if I knew where to find the script revision number.

Answer 2

Try:
brew update
then try it again. This appears to be fixed now.
