Should I worry about this warning when installing mingw-w64 on 10.6.8?

It is interesting that you were able to build i686-w64-mingw32-gcc-bootstrap @9.2.0 on 10.6. Our regular gcc9 port is programmed to error out on 10.6 and earlier saying it doesn't work. But if i686-w64-mingw32-gcc-bootstrap @9.2.0 works on 10.6, maybe the normal gcc9 @9.2.0 would work too.

It is expected, and it is just a notification to you that, unlike most ports which confine their file installations to /Applications/MacPorts and a small standardized list of directories within /opt/local, this port does not, for whatever reason. All of the cross-compiling gcc ports do this because they install to a nonstandard directory within /opt/local, presumably so that they do not conflict with the normal non-cross-compiling gcc.
