I don't have a 9.1-RELEASE system nearby, but I think zlib 1.2.7 _should_
already be there...  Are you sure it's still an old version?

The zlib on /head is 1.2.7, merged from the vendor branch on 2012-06-21.

This was later merged to 9.1-STABLE after about a week of burn-in on /head:

| % svn log --limit 1 svn://svn.freebsd.org/base/stable/9/lib/libz

| 
| MFC r237410: zlib 1.2.7.

Then the 9.1-RELEASE branch was copied from releng/9.1 on 2012-12-03, long
after the MFC of zlib 1.2.7 to the stable/9 branch.

I'm confused now.  By tracking down these commits in our svn repository I would
expect libz on 9.1-RELEASE to be version 1.2.7.
