SVN 1.7 for Mac OS Lion

Mac OS Lion comes with SVN 1.6 installed by default. But I needed to install SVN 1.7 to work on a project that uses SVN1.7.

Here is what I did to come trough:

I like using the SVN GUI tool svnX. The current version of the program is: svnX 1.3.3 ( Take a look and download it if you like what you see. It’s free and after you learn how to use it you will love it!. Download here.

The latest version of subversion is 1.7.5 (as today) and it can be found in

But svnX 1.3.3 is compatible with svn 1.7.4 so we are going to install that rather that the latest svn (1.7.5). Also I because I found some problems with svn 1.7.5.

1) Create a folder where you will put the svn 1.7.4 files. Download and extract the source.

$mkdir ~/Downloads/svn
$cd ~/Downloads/svn
$curl > ./subversion-1.7.4.tar.gz
$tar -xvjf subversion-1.7.4.tar.bz2  //to uncompress a bzip2 tar file: .tbz or .tar.bz2
$cd subversion-1.7.4

Configuration setup, Building and install the binary

$./configure --prefix=/usr/local
$sudo make install

It should now be installed in /usr/local/bin/svn. Check if it got correctly installed.

$/usr/local/bin/svn --version


  • You may try to install version 1.7.5 at your risk. Replace ‘subversion-1.7.5.tar.bz2’ with the latest version you find in the above link on the ‘curl’ command.
  • You can also install the latest version of subversion using MacPorts


Python, VPython and Enthought

For those who are starting to work with Python this may be useful.

I have been trying to use VPython for a while with the Enthought distro to develop Python software. (I’m using 32 bit Python 2.7 Enthought distro for Mac OSX 10.6.8).

But for some reason the VPython package will not be installed if the Python distribution in your mac is not the official one (e.g. oficial Python 2.7 installed in /Library/Frameworks/Python.framework/Versions/2.7)

The Enthought distro installs itself in


as a symbolic link to


Which is not right for VPython because it expects the default link to be ‘2.7’.

Ok, what I did was to delete the official 2.7 Python distro and create a symbolic link ‘2.7’ to the ‘7.2’ EDP version. And it works great!

To create the symbolic link just open the terminal and do:
>> cd /Library/Frameworks/Python.framework/Versions
>> sudo ln -s 7.2 2.7

Now open Python:
>> python

and type
from visual import *

you should see a sphere draw like this:

Now Python works well with Enthought.
