I am trying to follow the directions on the page
http://sagemath.org/doc/numerical_sage/installation_osx.html
to install the visualization software in an os-x (10.6.3) installation
of sage 4.6.1 and absolutely nothing there works. Running
cd $SAGE_ROOT/local/lib
rm libpng*.dylib
from the terminal, severely breaks sage, as it starts up with a very
long string of error messages (pasted at the bottom of this post). It
then can't even recognize the command "install_package", or even
"2+2". If I instead try removing those files after starting sage, I
can try the line
install_package('python-2.5.1-framework')
but it says the package can't be found. In fact, I get the same error
when trying to install any of the other packages mentioned on this
page, such as vtk, scitools or mayavi.
I have had the exact same problems in sage 4.6, running on 10.4 and
10.5 as well. I somehow feel this page is very out of date, as I
followed some of the instructions on the related page
http://sagemath.org/doc/numerical_sage/installation_linux.html
to find out what installation of python I'm running, and it came back
with
sage: !ls spkg/standard | grep python
ipython-0.9.1.p0.spkg
python-2.6.4.p9.spkg
python_gnutls-1.1.4.p7.spkg
But it even says that the package 'python-2.6.4.p9.spkg' can't be
found.
Can anyone help out here?
Thanks,
Jon
Here is what happens when I run sage from the command line after
running "rm libpng*.dylib"
