openssh upgrade help

[Paul JURCO]

Hi,
I have FreeBSD 5.0-RELEASE-p7 and i'm trying to patch openssh.
I used cvsup to get latest sources for RELENG_5_0.
#cd /usr/src/secure/lib/libssh
#make depend && make all install
Warning: Object directory not changed from original
/usr/src/secure/lib/libssh
make: don't know how to make
/usr/src/crypto/openssh/openbsd-compat/basename.h. Stop
#make depend
#make all
Warning: Object directory not changed from original
/usr/src/secure/lib/libssh
make: don't know how to make
/usr/src/crypto/openssh/openbsd-compat/basename.h. Stop

How can I upgrade openssh in this conditions?

Thank you,
