Advice on installing bzr-svn on Debian Stable

[Matt Doran]

Hi all,

Does anyone have any experience getting bzr-svn installed and working on 
Debian Stable/Lenny?    The core bzr package is available in backports 
(2.0.3), but bzr-svn isn't.

I tried installing the plugin into ~/.bazaar/plugins, but it has a 
dependency on subvertpy.    I tried doing a manual install of subvertpy, 
but when trying to build this I get errors like: "Exception: apr-config 
not found. Please set APR_CONFIG environment variable".   I think I'm 
starting to get out of my depth here. :(

Anyone have any tips?  Or even better the debs for bzr-svn and subvertpy 
for Debian stable. ;)

Regards,
Matt
