"port contents py27-ipython" will show you what was actually installed;
like most python ports, it's probably put stuff in the framework's bin
directory, somewhere under /opt/local/Library/Frameworks, and you will need
to add that to $PATH yourself.  (I do not know why that's how it's done.)

The thing you found is the package archive.  When you build a package (or
download it), you get that; then "port activate" is used to unpack it into
the installed ports tree.  You can "port deactivate" it and then activate a
different version, if you need to (unless you use -u, old versions are
retained when you upgrade ports, so you can easily recover if a new version
is buggy).
