Found this today with python-basemap. Numpy 1.4.0 introduced some ABI changes. Anything that compiles against numpy and hasn't been rebuilt since Numpy 1.40 was introduced in late January may need to be rebuilt in F-13 and rawhide. Just a friendly heads up. I'm fixing python-basemap now and then I'm going to start working through the rest of the potentially affected packages and firing up rawhide rebuilds for those with build times older than the numpy 1.4.0 introduction. Once that is complete I'll be looking at pushing F13 updates. Apologizes to anyone's toes. I'm hoping some of the affected maintainers see this and take care of this before me. Because this is an ABI break, this will show up in weird unexpected runtime breakages for users..some easy to hit...some not. Its best to just do rebuilds now to avoid trying to to track this down in a series of head scratching crash reports. -jef Here are the packages that might be affected according to repoquery run on my 32bit box with build timestamps prior to numpy 1.4.0. gnuplot-py healpy pygrace python-nltk reinteract PyOpenGL gnome-applet-music scitools scitools-extras fonttools pygame PySBIG pygsl ScientificPython python-matplotlib scipy python-biopython PyQuante gausssum expendable PyQwt plplot pyfits python-numdisplay inkscape rpy specto gnuradio python-cclib python-networkx getdata-python mypaint python-fiat Mayavi -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
