which: no g77 in (/sbin:/usr/sbin:/usr/lib/portage/bin:/bin:/usr/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.0.3:/opt/blackdown-jdk-1.4.2.03/bin:/opt/blackdown-jdk-1.4.2.03/jre/bin:/usr/bin:/usr/kde/3.5/sbin:/usr/kde/3.5/bin:/usr/qt/3/bin:/opt/oracle/product/10.2.0.1/bin) * No fortran compiler found on the system! * Please add fortran to your USE flags and reemerge gcc! gcc is compiled with fortran support, the only problem is that it looks for g77 instead of gfortran (which is the new naming scheme). A workaround is # ln -s /usr/bin/gfortran /usr/bin/g77
Which version?
