You can download the actual svn-sources from server using the svn command.
Exactly what I'm looking for. It's downloading now. Many thanks. Just a thought, but it might be worth someone putting some info about that on the download page while the nightlies are standard practice
Now I've got another problem. Running ./configure I run into this:
./configure: line 24298: AM_OPTIONS_WXCONFIG: command not found
./configure: line 24299: syntax error near unexpected token `2.8.0,'
./configure: line 24299: `AM_PATH_WXCONFIG(2.8.0, wxWin=1)'
From what I've read, this is resolved by installing wxgtk-dev, but that package is not available on the Arch repositories, and I don't know where else to find it. There seems to be no direct mention of it on the wxwidgets site.
Edit: Ah, looks like there are instructions for installing wx from source on that wiki page.
