Yes, MacPorts, for the most part, selects to install its own software
rather than relying on the system. The primary reason for this is
maintaining compatibility in the event that the system changes the
installed version of a tool that breaks compatibility with an old
version.

You can set this using "port select".
"port select --list perl"
"port select --show perl"
"port select --set perl <version>"

That "^M" is the issue. Try running "dos2unix" (also available in
MacPorts) on the file and run it again. The shell is interpreting the
line ending as part of the path.
