I was trying to import the subversion repository for our central application to git tonight, and I ran into some problems.
First, I tried to install the svn2git gem, but i kept getting:

ERROR:  could not find gem svn2git locally or in a repository

and James Coglan doesn’t have github gems enabled on the repository. So I had to clone the repository and install the gem manually.

% git clone git://github.com/jcoglan/svn2git.git

Sweet. So let’s try this thing out. Following the README file, I try

% svn2git http://svn.myserver.com/app
git: 'svn' is not a git-command. See 'git --help'.
git: 'svn' is not a git-command. See 'git --help'.
fatal: Not a git repository
fatal: Not a git repository

Well. Crap.

I do a bit more digging, and try to convert it the normal way, with git svn clone -s but get the same thing. As it turns out, according to Fat Penguin, when I installed git-core from MacPorts i didn’t use the +svn flag, so git-svn wasn’t installed with the rest of git. So here I go back MacPorts and

% sudo port deactivate git-core @1.6.0.2_2+doc
--->  Deactivating git-core @1.6.0.2_2+docs
% sudo port install git-core +svn
....bunch o' install crap....
--->  Activating git-core @1.6.0.5_0+doc+svn
--->  Cleaning git-core

and finally…

% svn2git http://svn.myserver.com/app

and BOOM! my svn repo is cloned into my current directory. Unfourtnatlly my current directory happend to be my projects directory. so i had app, config, db, etc… in the same folder as the rest of my projects. But after a little cleanup I had a git repository ready to work in, with my subversion logs still intact.
