Software GNUPlot not launching from GNU Octave

I'm trying to launch GNUPlot from Octave, but when I do I get the following error:

First I tried this:

mkoctfile

Since OS X 10.6, the Apple shipped version of gcc builds 64bit binaries by default. As the libraries included with Octave.app version 3.2.3 are 32bit, you need to apply the following patch in order for mkoctfile to work:
1. Open the folder /Applications in the Finder
2. Right-click on Octave.app and select "Show Package Contents"
3. Navigate to /Applications/Octave.app/Contents/Resources/bin
4. Right-click on the file mkoctfile and select Open with → Other… → TextEdit.app
5. Right after the line:
```
# along with this program; If not, see <http://www.gnu.org/licenses/>.
```
add the lines
```
 CFLAGS="-m32 ${CFLAGS}"
FFLAGS="-m32 ${FFLAGS}"
CPPFLAGS="-m32 ${CPPFLAGS}"
CXXFLAGS="-m32 ${CXXFLAGS}"
LDFLAGS="-m32 ${LDFLAGS}"
```
and save.
Gnuplot.app

An update to system libraries introduced with OS X 10.6.5 has broken the functionality of the Gnuplot.app included with the Octave.app distribution, in order to use Gnuplot.app on OSX 10.6.5 and later, you can use the fix described below:
1. Open the folder /Applications in the Finder
2. Right-click on Gnuplot.app and select "Show Package Contents"
3. Navigate to /Applications/Gnuplot.app/Contents/Resources/bin
4. Right-click on the file gnuplot and select Open with → Other… → TextEdit.app
5. Change the line:
```
DYLD_LIBRARY_PATH="${ROOT}/lib:${DYLD_LIBRARY_PATH}"
```
to
```
DYLD_LIBRARY_PATH="${ROOT}/lib"
```
and save.

After that didn't work, I double checked to see I typed the correct information. After that didn't work, I installed MacPorts and used it to install Octave and GNUPlot. That hasn't cleared it up either.

I'm running OS X Lion 10.7.3

The current way of installing octave and gnuplot is using a package manager such as Homebrew; it's really just a few commands and you're done; see http://wiki.octave.org/Octave_for_MacOS_X#Homebrew
