The HPUX linker is correct here in that dvdcss_interface_2 isn't a 
function symbol (it's a string symbol).  The reson that I test for
dvdcss_interface_2 and not dvdcss_open though is that that is the only
new symbol in the library over the 0.0.x versions.

So we need some other way to test if we have the new version of
libdvdcss instead, not just making a weaker test on HPUX.
Could you try 

AC_TRY_LINK([#include <dvdcss/dvdcss.h>], [char **v = &dvdcss_interface_2;], 
    [ CSS_LIBS="-L$dvdcss_path/lib -R$dvdcss_path/lib -ldvdcss"
      CSS_CFLAGS=-I$dvdcss_path/include ],
    AC_MSG_ERROR(You need libdvdcss.so.2 or later)
    )

instead of the following code

AC_CHECK_LIB(dvdcss, dvdcss_interface_2,
    [ CSS_LIBS="-L$dvdcss_path/lib -R$dvdcss_path/lib -ldvdcss"
      CSS_CFLAGS=-I$dvdcss_path/include ],
    AC_MSG_ERROR(You need libdvdcss.so.2 or later)
    )

The other case without the path would also have to be chaged in the same
way if it works.
