Basically Solaris does not ship with a new enough version of gcc - in fact, the gcc it ships with does not even have Fotran support at all. So somehow you need to get the libraries that Sage uses, which includes the Fotran library libgfortran.so. But you can get it several ways. If you have a recent gcc that is built with Fortran support, it will have a file libgfortran.so. You can copy or link that file to $AGE_ROOT/local/lib/libgfortran.so, where SAGE_ROOT is the directory where you installed Sage. You could also trying add the installation directory of gcc to LD_LIBRARY_PATH - something like LD_LIBRARY_PATH=/usr/local/gcc-4.5/lib One other option, which might be easiest for you, is if we make available a set of the gcc libraries used to build Sage. I think that might be a good idea. I can't do that just now, but can do it within 24 hours or so. I'm just about to go out to the London OpenSolaris User Group (LOSUG), so don't have time to make any binaries now!!! But I can do it soon. Let me know how you get on. The binaries for Solaris are a few months old. We can make some newer ones available, but that might take a bit more time. Getting your Sage working should not take long. You don't need the help of your system admin, but it might help if we make the libraries available, which we can do under the terms of the LGPL which covers the libraries built by GCC.
