That should probably be
  setenv  LIBXML_INCDIR -I/usr/local/include/libxml2

(rather than having the additional /libxml after it.)

Did you install libxml2 version 2.7.3 yourself,
i.e. separately from the installation of the operating system?
Is /usr/local/lib being searched for .so files by your dynamic
loader?

Try

   ldd `which xmllint`

to see what shared libraries it finds? Does it list
libxml2.so.2 and if so, where is the file to which it points -
/usr/lib or /usr/local/lib ? If it is /usr/lib, that is the
problem.

If this doesn't identify the problem, please download
the XML_2.3-0.tar.gz file and issue the commands

   tar zxf XML_2.3-0.tar.gz
   R CMD INSTALL XML

and send me the file XML/config.log and I can try to
find out what is going wrong form the details in that.

Thanks,
   D.
