Goal: Installing some R packages requires understanding what libraries are available on the System.

You are trying to use a version 2.* edition of libxml but an incompatible library. The header files and library seem to be
mismatched. If you have specified LIBXML_INCDIR, make certain to also specify an appropriate LIBXML_LIBDIR if the
libxml2 library is not in the default directories.

What does the error message mean?
How to Resolve XML Package Issue
We can see from the CRAM package XML description that from the System Requirements we require: libxml2 (>= 2.6.3)
We can see that the libxml2 library is available and is being picked up.

Sometimes the cause of the error isn’t obvious.

Install the R sf Package
Reading the CRAN sf definition page, take note of the system requirements:
System Requirements: GDAL (>= 2.0.1), GEOS (>= 3.4.0), PROJ (>= 4.8.0), sqlite3
What do we already have loaded?
[salexan5@mblog2 ~]$ ml Currently Loaded Modules: ... 35) sqlite/3.43.2 76) scrnsaverproto/1.2.2 ...
We also need to manually load:

Configuration failed because libudunits2.so was not found. Try installing:
* deb: libudunits2-dev (Debian, Ubuntu, ...)
* rpm: udunits2-devel (Fedora, EPEL, ...)
* brew: udunits (OSX)
If udunits2 is already installed in a non-standard location, use:
--configure-args='--with-udunits2-lib=/usr/local/lib'
if the library was not found, and/or:
--configure-args='--with-udunits2-include=/usr/include/udunits2'
if the header was not found, replacing paths with appropriate values.
You can alternatively set UDUNITS2_INCLUDE and UDUNITS2_LIBS manually.

You will need to load all module(s) on any one of the lines below before the "udunits/2.2.28" module is available to load.
