OpenSSH SRPM compile

[Purcell, Christopher J]

I'm trying to compile openssh-3.6.1p2-33.30.3.src.rpm (from RHEL3) on a
RH73 server.    After running 'rpmbuild -bb SPECS/openssh.spec', it
fails towards the end of the compile with this.... 
 

sshd.c: In function `sshd_exchange_identification':
sshd.c:372: `SSH_VENDOR_PATCHLEVEL' undeclared (first use in this
function)
sshd.c:372: (Each undeclared identifier is reported only once
sshd.c:372: for each function it appears in.)
sshd.c: In function `main':
sshd.c:991: `SSH_VENDOR_PATCHLEVEL' undeclared (first use in this
function)
make: *** [sshd.o] Error 1
error: Bad exit status from /var/tmp/rpm-tmp.4509 (%build)
 

RPM build errors:
    Bad exit status from /var/tmp/rpm-tmp.4509 (%build)
[root at usilws22 SPECS]#

 
 
 
Any ideas on how to get around this issue?
 
 
Thanks,
Chris
