First uninstall the installation I have made that results in this error:
$ svn --version
svn: Mismatched RA version for 'dav': found 1.4.3, expected 1.4.2
Next install Trac using the latest instructions at [url removed, login to view] instead of the out of date instruction I used at [url removed, login to view] - this no longer works due to APR incompatibility.
I have attached my "failure" log if you're interested.
Then import a sample project so it is visible to trac and svnclients.
Then budget for 3 or 4 hours post install support, divided into half a dozen IM sessions or emails, please.
I will of course provide all access for ftp/ssl/db for the succesful bid.
