'port provides $(which updmap)' if you have it installed. If not, there
is no way to find this out. As MacPorts is building from source there is
no way to know which files it will install before building.

Yes, it will be overwritten.

The first one is the current "active" copy. The other one is in the
image where everything gets installed first. At 'port activate'
hardlinks are created in the prefix to the files in the depot. You can
read more about images at <>.

I would recommend to copy the file to ~/texmf/web2c/updmap.cfg in your
home and edit it there. I am doing the same for some local latex styles
(although I am using texlive).

Configuration file handling in general is a mess in MacPorts at the
moment. If they were part of the port, an upgrade would simply overwrite
them. So for most ports you have to copy the default configuration
manually and edit it.
