If you get
checking for svn includes... configure: error: failed to find svn_client.h
Try
sudo apt-get install libsvn-dev

For install in CentOS 5.5
yum install subversion subversion-devel neon neon-devel
pecl install svn
echo "extension=svn.so" > /etc/php.d/svn.ini
service httpd restart

If you have Ubuntu (I know 10.04+, not sure about earlier), you can do this to install the package;
sudo apt-get php5-svn

If you use CollabNet's Subversion client (v. 1.6.13), the development libraries are included. For the most current version (v 1.6.17) you may need to install CollabNet Subversion Edge for access to the development libraries.
Sure, the subversion-devel package should not conflict with Collabnet, but it has a dependency with the subversion package, which installs svn binaries in /usr/bin, which takes precedence over CollabNet's path in the PATH environment variable.

For Windows:
If you use a fresh install of windows XP you will need all this DLL in your C:/windows/system32/ folder:
intl3_svn.dll, libdb43.dll, libapr.dll, libapriconv.dll, libaprutil.dll, libeay32.dll, msjava.dll, php5ts.dll, ssleay32.dll, vsinit.dll, msvcr71.dll, MSVCP71.DLL
I recommend to use DependencyWalker (http://www.dependencywalker.com/) with your php_svn.dll (in php extensions) to see exactly which ones you need.
