SSH compatibility issue with Git

Question

After updating Macports today with

$ sudo port upgrade

Git can't push

$ git push
OpenSSL version mismatch. Built against 1000005f, you have 1000100f
fatal: The remote end hung up unexpectedly

$ ssh -version
OpenSSH_5.9p1, OpenSSL 1.0.1 14 Mar 2012
Bad escape character 'rsion'.

$ uname -a
Darwin foobar.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun  7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386

Anyone else? How to fix this quickly? (This is stopping me from doing useful work.)

Edit: errors I get after rolling back git-core and open-ssl ports:

$ port installed git-core openssh

The following ports are currently installed:
  git-core @1.7.5.1_0+doc+python27

Answer 1

sudo port deactivate the openssl, openssh, and possibly git-core ports, and sudo port activate the old versions. (port installed openssl git-core openssh to see these old versions.) Although I thought this had already been fixed; did you port selfupdate first?

Answer 2

Trying updating your openssh (which git is using).

$ sudo port upgrade openssh

I found that at the very end of this thread: installing git-core (to upgrade OpenSSL) leads to errors
