TSearch2 snowball version error

Hi,

I'm trying compile a new brazilian portuguese dictionary to TSearch2
contrib, but found the errors:

make: ** [portuguese_stem.o] Erro 1

This after change the included file "header.h", the old
"../runtime/header.h" is invalid.
I think that is a version trouble, because the return of functions
"slice_from_s" and "slice_del" are "int" in current snowball portuguese
files, but on include files of version 8.0.2 and 8.0.3 of Portgresql the
return type is "void".
Help-me, please.
