It has been a while, but there is a new release of smeserver-subversion. The package fixes the following bugs:
On top of that I moved the package to the SME Server CVS. As a effect of that the package is now available in the SME dev repository, this means you should be able to install SubVersion for SME Server like this from the SME Server shell:
yum install smeserver-subversion
Upgrading from previous versions should not be a problem, if for some reason you have issues with this contrib please post your remarks and comments in the SME Contribs section of the SME Server bugtracker.
