I use something similar to:

    AC_PATH_PROGS([TOOL_XML2_CONFIG], [xml2-config])
    AS_IF([test -n "$TOOL_XML2_CONFIG"],
          [XML2_CFLAGS=`$TOOL_XML2_CONFIG --cflags`
           XML2_LIBS=`$TOOL_XML2_CONFIG --libs`],
          [AC_MSG_ERROR([missing program 'xml2-config'; is 'libxml2' or 
'libxml2-devel' installed?])])
    AC_SUBST([XML2_CFLAGS])
    AC_SUBST([XML2_LIBS])

You could use a variation of this to obtain the version.


cheers,
Luke.
