The two installs have separate paths and can co-exist just fine.

You have to set your ROS_PACKAGE_PATH correctly to access one or the other.

Because that depends on environment variables, switching back and
forth is cumbersome and confusing. I don't know a good method to
recommend. I usually switch by editing my ~/.bashrc and then running
"source ~/.bashrc" in each open terminal window.

There must be a better way. Perhaps some of the WG folks can suggest
"best practices" for testing with multiple releases.
