 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest

Не впевнений, у чому тут проблема. sudo yum install libRmathкаже мені

Package matching libRmath-2.15.2-1.el5.x86_64 already installed. Checking for update.
Nothing to do
