Build issue for git 1.8.5.1 under Mac OS X 10.8 (Mountain Lion)

Hi all,

Over the years I have built many versions of git and released them on hmug.org. git 1.8.5.1 builds just fine under OS 10.7 (Lion) and 10.9 (Mavericks), but the build fails (also for 1.8.5) on 10.8 (Mountain Lion):

Apparently a header issue: I tried force feeding the Security/SecEncryptTransform.h file, and just got an other error…

Any help would be welcome!

Thanks in advance.
