Ledger is no longer going to be tracked under Subversion from this point forward. Instead, if you wish to obtain the latest sources, clone a copy from the Git repository:
git clone git://newartisans.com/ledger.git
Boost 1.34 was released today, and I'm moving to it right away. This means that to build the current SVN head, you'll need to get this version of Boost from http://boost.org and build it. I hope that by the time Ledger is ready for its next release, this version of Boost will be common through most Linux package installation systems.
I have removed support for CVS and moved all of the sources to Subversion, which I'm find to be much easier for managing local changes and handling branches. Please check out the sources from Subversion if you wish to follow current development. You can check out 'ledger/branches/ledger-3-0' if you wish to follow 3.0 (which may remain broken for some time).
Due to that fact that it was under-documented, poorly supported, and effectively used by no one (myself included), I have completely removed Python integration support from Ledger. Emphasis will now be placed on using the "xml" and "csv" reports for manipulating Ledger's output data, rather than embedded scripting.
