Installing R from yum on AIX is missing a dependency on downlevel libgfortran.a

yum upgrade installs newer versions of libssh2, curl, and python along with their new dependencies on gcc and gcc-cpp, which installs gcc 8.1.0, which in turn conflicts with gcc 6.3.0

Oh !!, Seems like the latest gcc-gfortran is only having "libgfortran.so.5" . We will fix this soon in gcc-gfortran rpm.

As a workaround you can downgrade gcc to 6.3.0 version and install R.
