Problems installing Octave on osx 10.6.8

[George Profenza]

Hello,

I'm currently trying to install Octave and am experiencing some issues.

Here's what I tried:

I've installed Octave via Macports - Octave itself works, but even though Macports reports gnuplot and aquaterm were installed using functions like stem() or plot() 

seem to be ignored (as if there is no link between Octave and GnuPlot or GnuPlot can't open a window, but I'm not getting any errors)

I've also tried the osx bundle and have installed http://www.miscdebris.net/upload/gnuplot-4.2.5-i386.dmg as advised on the wiki,

but I got these errors:

[code]

[/code]

I presume the libTIFF and libJPEG bundled in the ImageIO frameworks aren't compatible with Octave ?

I should have other version of the dylibs installed by Macports when I installed ffmpeg/opencv. 

Is there a way to tell Octave to look for the dylibs in /opt/local/lib rather than the system frameworks ?

Any hints/tips on how I can get Octave running with Gnuplot ?

Thank you for your time,

George
