If you use the binary MacPorts installer, it modifies the PATH in your startup script, if the PATH does not already contain the MacPorts paths. Which startup script it modifies depends on which one(s) you have and what your user's shell is.

It is highly recommended.

The binary installer does not give you the option to select the prefix. It is fixed at /opt/local. I considered finding a clever way to allow the installer to let you choose a prefix, but I set that idea aside once we started offering binaries, since the binaries are built for /opt/local only.

You can set a different prefix by compiling from source instead of using the binary installer, but then you miss out on binaries, and may encounter other bugs in ports which assume your prefix is /opt/local.

That approach is untested and unsupported.
