Unable to install ports from git source as root : Could not open file

[Joël Tourscher]

Hello,

I'm trying to use macports and ports from git sources. I have followed 
the instructions from the 
[https://guide.macports.org/#installing.macports.git manual], but it 
doesn't work.

The port macports-base compiles well, but it is impossible to install 
any port as root (as well as user). I have an error message.
  - As sudo : /"Error: Unable to execute port: Could not open file: 
macports-ports/sysutils/coreutils/Portfile"/
  - As user : /"Error: Insufficient privileges to write to MacPorts 
install prefix."/

I need to chown the macports-base tree to the user who is running the 
port, and then most of them can compile, but only as user, and not as root.
     sudo chown -R $UID:$GROUPS $MACPORTS_DIR/macports-base
     sudo chown -R $UID:$GROUPS $MACPORTS_DIR/macports-ports


Some of ports still need to have root access, and cannot be installed 
(eg libnetpbm) and then cannot be installed.

The error message is : /"Error: Failed to destroot libnetpbm: command 
execution failed"/

Note that this seems to work if instead of using a subdir of $HOME as 
root for projects, a subdir of /tmp is used to build the ports.

Here is a script that simulates the test cases.

Regards, Joel
