When trying to install R 3.3.0 with zlib 1.2.11 on the system, we get:
checking zlib.h usability... yes
checking zlib.h presence... yes
checking for zlib.h... yes
checking if zlib version >= 1.2.5... no
checking whether zlib support suffices... configure: error: zlib library and headers are required
This is because there's an assumption in configure
that the zlib is x.y.z
with only five (5) characters total.
A patch is:
diff -w -u configure.R-3.3.0 configure

Fix the
Makefile
so it can install also R (<= 3.3.0) on Rocky 8.https://cran.r-project.org/src/base/R-3/:
make check
error, but R works)
