If I tried to start R after gcc upgrade to 4.6.3, it fails with: root@impala:/root(22)# R /usr/lib64/R/bin/exec/R: /usr/lib64/gcc/x86_64-pc-linux-gnu/4.5.3/libgfortran.so.3: version `GFORTRAN_1.4' not found (required by /usr/lib64/libf77blas.so.3) After reemerging sci-libs/atlas and R it works again: root@impala:/root(28)# genlop -t atlas | tail Tue Feb 21 01:50:52 2012 >>> sci-libs/atlas-3.9.67 merge time: 15 minutes and 40 seconds.

(In reply to comment #0) > After reemerging sci-libs/atlas and R it works again: So where's the bug here? You've switched gfortran version, compiled atlas. This made atlas require newer libgfortran and then you've used R which was compiled with old libgfortran. Both of them were loaded at R's runtime and clashed... Please read gcc upgrading guide[1]. Whatever is written about C++ ABI there applies for fortran as well. [1] http://www.gentoo.org/doc/en/gcc-upgrading.xml
