error compiling on HP-UX 11i

[Pad Hosmane]

Hi,
  I am compiling SpamAssassin-3.1.0 on HP-UX 11i, with perl 5.8.8. I have
installed most of perl modules, except these perl modules are not installed

optional module missing: Razor2
optional module missing: Net::Ident
optional module missing: IO::Socket::INET6
optional module missing: IO::Socket::SSL


During the compile of SpamAssassin I get the following error and exits

 
cd .. && make -f spamc/Makefile everything
        gcc  -Wall -g -O2 spamc/spamc.c spamc/libspamc.c spamc/utils.c \
                -o spamc/spamc   -lnsl 
spamc/spamc.c: In function `combine_args':
spamc/spamc.c:431: error: `EX_CONFIG' undeclared (first use in this
function)
spamc/spamc.c:431: error: (Each undeclared identifier is reported only once
spamc/spamc.c:431: error: for each function it appears in.)
*** Error exit code 1

Stop.
*** Error exit code 1

Stop.


Can anyone help me in this regard?

Thanks in advance.
