Do you really need to install from source? The EPEL RPMs by Tom
Callaway from Redhat contain a bundled version of zlib for platforms
that do not have an up-to-date system version, and so are much easier
to install.

Note that it is not only zlib that is affected. You will have the same
issue for bzip, xzv, pcre, and curl.

This information is contained in the "R Installation and
Administration" manual, also known as "R-admin". The minimum version
required is zlib 1.2.5.  You can also see this information in the
output from configure, e.g. on my system:

checking if zlib version >= 1.2.5... yes
