That one is definitely not from a newer git. What do you do in between
the two steps above and below, where the same command "git version"
returns different results? You must have some older parts lying around
somewhere, whether they get picked up by on old or new git svn or Git.pm.

What do the following say:

which git-cat-file
which git
git --exec-path
#desperate last attemtp
find / -name git-cat-file | xargs -n 1 sh -c
