There must be some local issue on your system that makes it non-standard.
There are literally hundreds of us running this R version and built every day
from the same binaries.
The best clue is
error: /usr/local/lib/libreadline.so.6: undefined symbol: PC
which clearly indicates that you have a version of readline masquerading as
version 6 ... which is then used to run R but fails for incompatibility.
That is, sorry to be blunt, your fault and issue. Remove that library (with
some care, you could first rename or move to a hidden directory) and then run
'sudo ldconfig' to update the shared library cache used by the system. Then
try R. Or, as an alternative to running R:

As you can, nothing is pulled in from /usr/local and I run R against the
libraries provided by the package management system as it was meant to be
used.
You should get there too.
Hth, Dirk
