Using libxml2.*

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.
ERROR: configuration failed for package ‘XML’

How to Resolve XML Package Issue
We can see from the CRAN 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.
