Plotting with Octave after most recent MAC OSX update

Question

Hi I just recently downloaded the most recent snow leopard update. Then I tried to plot something using Octave which has been installed on my computer for months (and plotting has worked all that time) Even since I installed the update, and I try to plot using octave I get the following error:

dyld: Library not loaded: /usr/X11/lib/libfreetype.6.dylib

  Reason: Incompatible library version: libfontconfig.1.dylib requires version 13.0.0 or later, but libfreetype.6.dylib provides version 10.0.0

error: you must have gnuplot installed to display graphics; if you have gnuplot installed in a non-standard location, see the 'gnuplot_binary' function

I'm really not sure what to do. I'm way out of my league here.

The "note for MacOSX users" is no longer on the Octave homepage, and the workaround described in Marco's post didn't work for me either, but this did:

Open /Applications/Gnuplot.app/Contents/Resources/bin/gnuplot in a text
editor. Use the editor search-and-replace feature to replace
"DYLD_LIBRARY_PATH" with "DYLD_FALLBACK_LIBRARY_PATH". There are four
instances that need to be replaced.

This is from the readme for the Octave MacOSX Binary. Note that it says it's for Lion users, but I'm running 10.6.8 and it worked for me.
