I haven't figured out your particular error, but browsing through the build log revealed that the local copy of the sample data is incomplete:
/tmp/buildd/matplotlib-1.0.1/build/lib.linux-x86_64-2.7/matplotlib/sphinxext/plot_directive.py:322: PlotWarning: Exception running plot /tmp/buildd/matplotlib-1.0.1/doc/mpl_examples/pylab_examples/image_demo2.py Traceback (most recent call last): File "/tmp/buildd/matplotlib-1.0.1/build/lib.linux-x86_64-2.7/matplotlib/sphinxext/plot_directive.py", line 319, in render_figures run_code(plot_path, function_name, plot_code, context=context) File "/tmp/buildd/matplotlib-1.0.1/build/lib.linux-x86_64-2.7/matplotlib/sphinxext/plot_directive.py", line 230, in run_code "__plot__", fd, fname, ('py', 'r', imp.PY_SOURCE)) File "image_demo2.py", line 9, in <module> IOError: [Errno 2] No such file or directory: '/tmp/buildd/matplotlib-1.0.1/sampledata/ct.raw' In addition, the log also revealed a slight logical error on the part of upstream matplotlib, because it attempts to generate a basemap image, but matplotlib is not dependent on basemap -- minor issue, though. There are a few other build errors, but I believe they were fixed in subsequent revisions to matplotlib 1.0.x branch. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/607395 Title: Please merge matplotlib 1.0.1-1 (universe) from debian experimental main -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
