mercergeoinfo at yahoo dot co.uk changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mercergeoinfo at yahoo dot | |co.uk --- Comment #4 from mercergeoinfo at yahoo dot co.uk 2011-10-03 15:16:15 UTC --- I followed the instructions in the 3rd comment, actually I installed the suggested binary from the link in point 2 first but the problem persists. Looking at the contents of /usr/local/libexec/gcc/i686-apple-darwin8/4.2.3/ may give an answer, it contains an empty folder called "install-tools". Any other suggestions for getting gfortran to run on OSX (Lion)?
