Yes. I suffered from the same sorts of problem.
Two things to check first:

1) The new code requires TikZ version 2.0 or better.  My linux distro (Mandriva) 
doesn't have this yet even though it was released in 2007.  So I had to 
upgrade it manually.  In practice this meant downloading a current
version of the pgf package from CTAN:
   http://www.ctan.org/tex-archive/graphics/pgf/
I used it to replace the older version of pgf that I had in texlive-2007 and
everything worked with no problems.

If this is your problem, you should (I think) generate the following error message
when you try to process output from the new terminal in pdflatex:

  PGF/TikZ version >= 2.0 is required, but 1.18 was found


2) If you don't get that error message, it may mean that you are running an
old version of the TeX support code from the previous gnuplot installation. 
Make sure the TeX support packages for gnuplot were updated to match the
new lua terminal driver.  I.e. you may need to run texconfig after installing
the new gnuplot.
