Ubuntu comes with CouchDB 0.8.0-incubator. I have it running correctly. I've recently wanted to upgrade to 0.9.0, so I followed the instructions on this blog post, but I seem to be missing the final step. I downloaded the tarball, unzipped it, and called make & make install as the guide says. Every step completed successfully. When I then execute
/etc/init.d/couchdb start
it boots up 0.8.0 instead of 0.9.0. I must be missing some step where my freshly compiled 0.9.0 build replaces the 0.8.0 installation. I thought that's what "make install" would do, but it appears not.
