'emerge R' fails if "g77 fortran" is not present on the system. I guess that R is missing a dependency on "g77 fortran". Reproducible: Always Steps to Reproduce: 1. emerge R 2. 3. Actual Results: You can't compile R Expected Results: R should compile and work
Please always mention the version you are talking about. The problem is that portage currently does not allow DEPENDing on optional parts of other programs (like g77 as part of gcc). *** This bug has been marked as a duplicate of 56616 ***
