It's a really boring module which makes a frustrating dependency problem go away. What more could you possibly want from an Alien:: dist? Thanks to Schwern and Matthew for handling this bit of thankless plumbing.
The only thing I see wrong with this module is that some of its users report installation problems here on the CPAN ratings site instead of using the bug tracker ( rt.cpan.org/NoAuth/Bugs.html?Dist=Ali... .)
This module would benefit from an option to use the SVN libs already on the system. The bundled Subversion 1.4 (which is a bit old, actually) seems to be not installable on my Gentoo Linux (but I have 1.6.4 installed and working).
