All, I wanted to share this with the users.? I have been having periodic issues with packages loading with a missing gfortran.so.3 file.? I have found this is due to system upgrades to my fedora linux computers to a? newer version of gfortran. I am not sure if other linux flavors have this issue or not, but I expect if you do a major version upgrade it will happen. The fix is to re-install the packages that was linked to gfortran.so.3.? This is a real simple fix, only I don't know what packages are at issue to re-install all at one time, so periodically I have this issue appears much to my exasperation. If anyone knows how to determine all installed packages with a gfortran dependencies, then we could submit a short update script for this. Thanks Joe
