If you see this message when trying to svn up:
# svn checkout https://svn0.us-west.freebsd.org/base/release/8.4.0 /usr/src svn: E170000: Unrecognized URL scheme for 'https://svn0.us-west.freebsd.org/base/release/8.4.0'
then you are missing a subversion compile option. Try this command:
cd /usr/ports/devel/subversion && make config
Then make sure this option is checked:
[X] SERF WebDAV/Delta-V (HTTP/HTTPS) repo access module
Then recompile subversion with one of these two commands:
portupgrade -f subversion
Or
portmaster subversion
