Hi,

In response to Agus, I checked and saw that I had not cc'd the list.  
Hopefully this will get your students in order. Sorry for the oversight.

Regards,
John

Borys,

I'm not sure where on the wiki (qgis wiki?) this would go, but feel  
free to put it on for me wherever you feel it is appropriate. If you  
have the all-in-one qgis bundle, ymmv:

Value Tool Plugin on OS X:
(These instructions were performed on OS X 10.6.1, but should work on  
10.5+; not sure about tiger or older. I assume you have the Apple  
Developer tools, Qt, and other Qgis build requirements installed on  
your machine as per the Build from Source instructions for OS X.)

The gdal and osgeo modules are part of William's gdal framework, so  
make sure those are installed on your system. The value tool plugin  
requires pyqwt5 as well. To install this, first download the latest  
source (e.g., 'curl -O http://softlayer.dl.sourceforge.net/project/pyqwt/pyqwt5/PyQwt-5.2.0/PyQwt-5.2.0.tar.gz 
), and enter the source directory (I assume you have qwt source and  
pyqwt source in the same directory, e.g., your root or a temp  
directory). Enter the configure directory and edit configure.py with  
your favorite editor. Change line 186 from '    qmake = os.path.join 
(configuration.qt_dir, 'bin', 'qmake')' to '    qmake = os.path.join 
(configuration.qt_dir, 'usr', 'bin', 'qmake')', then save and run  
'python configure.py -Q ../qwt-5.2'. After this, 'make' and 'sudo make  
install' and your all set to install the Value Tool plugin from the  
Plugin Manager in Qgis.

Regards,
John
