Missing dependencies in pkg installs

I had the same thought in the shower this morning but I was disappointed to find that SElinux was disabled on the system.  My next step will be to install a previous version of R on the system.  My problem is that I am planning a shiny server installation and at least half of the apps on the current system depend on these libraries that will not install.

Just a thought - are you running SELinux ?
Check the log files for refusals to run programs.
