Those settings are for http/ftp proxies (like squid) and are understood
internally by most things that do http or ftp. However, the command above sets
up ssh as a socks proxy, and there is not a generic way to tell things to use
socks proxy in the environment. You either need to configure apps individually
to use a socks proxy or use something like runsocks that pushes a socks-aware
shared library in front of each app.
If there is a squid or similar proxy on the other end of the ssh connection you
could use port-forwarding to it, then export the environment variable settings
pointing to your locally-forwarded port.
