MacPorts will not use the PATH environment variable configured by the user at
all for building. These two examples should make no difference for MacPorts.
However, I do not know if having /opt/local/bin:/opt/local/sbin on PATH causes
problems for Homebrew.

This is the main problem. If you want to use Homebrew in parallel to MacPorts,
choose a different prefix than /usr/local.
