Yes, I was a sysadmin at UGA for a while, and I decided to get into
academic research, so I'm in the C.S. Masters program now.

I remember doing some work getting integrit to build cleanly on Mac OS
X, and I think that the CVS version may contain a fix for the problem
you were seeing in the md5 code preprocessing.  I'm not sure, though,
and I can't find a note to that effect in the CVS log.  Using the CVS
version is pretty easy, so you could see if it works better.  There
are instructions here:

The static option makes the linker try to produce a statically-linked
binary executable.  The alternative is an executable that is linked
with ld.so, and at runtime ld.so will try to dynamically find and load
libc.  So you could take the binary off the build machine and run it
on another Mac, especially if the shared libraries are the same on
both.  That's how most pre-compiled software is.

The statically-compiled integrit is traditionally preferred because of
the small chance that an intruder could modify the system's libraries
(and presumably not the kernel or integrit), in which case you'd be
better off with an integrit that didn't rely on the poisoned
libraries.
