libxml2, zlib, and/or the Math library (-lm) have not been found.
Try setting LIBS and INC values on the command line
Or get libxml2 from
http://xmlsoft.org/
If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.
Also, you may try to run perl Makefile.PL with the DEBUG=1 parameter
to see the exact reason why the detection of libxml2 installation
failed or why Makefile.PL was not able to compile a test program.
