This was discussed a few days ago on this very list. The correct
answer for redhat 7.2 is to install
By definition, symbolic libraries with different "sonames" (like
/usr/lib/libreadline.so.4.1 and ...4.2) may be incompatible, so
programs compiled for one of them shouldn't try to use the other. (Some
packages insist on letting the soname follow the release name whether
or not versions are binary compatible so there's no guarantee it would
Empirically it seems to work for R if you make the .4.1 lib a symlink
to the .4.2 lib, but there is no telling what that might do to other
