Compiling on RH8

[Jason Dunkerley]

Hi,

    I have successfully setup perlbal on some Centos 4 machines and want 
to now use it on some older RH8 machines.  Obviously, there are some 
differences between the two, but I'm not sure how to resolve this.  When 
I compile perlbal and run the make test, I get the following error:
<snip>
PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" 
"test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
t/00use....NOK 1#     Failed test (t/00use.t at line 
7)                     
#     Tried to use 'Perlbal'.
#     Error:  Undefined subroutine &main::SYS_sendfile called at 
/usr/local/src/Perlbal-1.2/blib/lib/Perlbal/ClientHTTPBase.pm line 41.
# Compilation failed in require at (eval 10) line 3.
#       ...propagated at /usr/lib/perl5/5.8.0/base.pm line 64.
# BEGIN failed--compilation aborted at 
/usr/local/src/Perlbal-1.2/blib/lib/Perlbal/ClientProxy.pm line 8.
</snip>

It goes on, but I'm pretty sure this is the part that is needed.  Any 
ideas what the problem is?

I have installed the prereq perl modules no problem.

Any help would be much appreciated.

Thanks,
