NetBeans has SVN support pretty much out-of-the-box, but on OS X you will be presented with the not so obvious message

NetBeans Subversion support requires Subversion 1.3 executable!

Install Subversion 1.3 (http://subversion.tigris.org) or later, add it to PATH, test by running ‘svn –version’ from command line, and finally restart IDE, please

Since I apparently has forgotten how I made it work before here is the instruction for future reference, hopefully this will save me (and perhaps others) from some frustration.

1. Fire up a terminal

2. Navigate to your Netbeans installtion folder like

cd /Applications/NetBeans5.5.app/Contents/Resources/NetBeans/bin

1. Open the netbeans file in your favorite editor

2. On the first line (after comments) add

PATH=$PATH:/usr/local/bin:/usr/local/sbin
export PATH

1. Save the file, and restart NetBeans

Your all set!
