I was setting up my subversion server on a Linux Ubuntu machine today. Not a simple task. However, setting up a Solaris subversion is not necessarily a simple one either. Solaris binaries can be found in one of two places:

• Sun Freeware - for Solaris 9.
• Open Collab Net - Available for Solaris 10.

For Solaris 10 it was simple.  Download the package.  Install as root (pkgadd -d).

Once installed:
/opt/CollabNet_Subversion/bin/svn import brixWorx svn+ssh://192.168.1.100/media/data/svn/brixWorx/

For Solaris 9, download from SunFreeware all the stuff you need.  The list is very long.  Download and install with pkgadd -d :

• apache-2.0.59 (for subversion 1.4.3) and apache-2.2.6 (for subversion-1.4.5)
• neon-0.25.5
• swig-1.3.29
• openssl-0.9.8f
• db-4.2.52.NC
• expat-1.95.5
• gdbm-1.8.3
• libiconv-1.11
• libxml2-2.6.26
• zlib-1.2.3

Command:
/usr/local/bin/svn import serviceDirector svn+ssh://192.168.1.100/media/data/svn/serviceDirector/

In either case you probably need your environment to have:
SVN_EDITOR=/bin/vi
export SVN_EDITOR
