#57894: Unable to install ports from git source as root : Could not open file
 Reporter:  toki07  |      Owner:  (none)
     Type:  defect  |     Status:  new
 Priority:  Normal  |  Milestone:
Component:  base    |    Version:  2.5.4
 Keywords:          |       Port:

 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:
  - 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
 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.
