phantomjs @2.0.0_2: still broken port after rebuilding it more than 3 times

[JDLH (Jim DeLaHunt)]

MacPorts 2.5.3, Mac OS X 10.11.6.

When attempting to upgrade port inkscape, macports discovered broken port phanthomjs, and was unable to correct it.

Error: Port phantomjs is still broken after rebuilding it more than 3 times.
Error: Please run port -d -y rev-upgrade and use the output to report a bug.
Error: rev-upgrade failed: Port phantomjs still broken after rebuilding 3 times
Error: Follow https://guide.macports.org/#project.tickets to report a bug.

Building phantomjs three times takes many minutes and pegs the CPU at maximum. I went around this merry-go-round several times before filing this ticket.

Output from port -d -y rev-upgrade attached.

There is no logfile available. Maybe this is because the failure is a "broken port", not a "build error".

% port logfile phantomjs
Error: Log file for port phantomjs not found

phantomjs does run, at least minimally:

% phantomjs --version
2.0.0

Output from running sudo port -d -y rev-upgrade with broken port phantomjs

[jmroot (Joshua Root)]

phantomjs is using libstdc++ (this installation is configured to use libc++)

[JDLH (Jim DeLaHunt)]

Thank you for that observation. However, I'm not sure what to do with it.

You say, "this installation is configured to use libc++". I do see a statement to his effect in the output from port 'rev-upgrade`:

....
--->  No broken files found.
phantomjs is using libstdc++ (this installation is configured to use libc++)
--->  Found 1 broken port, determining rebuild order
DEBUG: Broken: phantomjs
....

(That message doesn't scream "here's your problem" to me. I'm glad you know enough to interpret it.)

I don't know what to make of "is using" and "is configured to use". Does this message mean that the phantomjs port needs to use to use libstdc++, but the port supplies it with libc++, which is a bug in the port, and the port should be changed to use libstdc++? Or are you saying that my individual installation is configured to use libc++, so I need to change my installation somehow?

In either event, I would be gratful if someone perhaps could provide a pointer to further explanation about how to fix the problem. I've looked through my portfile and patch files for phantomjs, and see no mention of either libc++ or libstdc++. I haven't asked for any special configuration of phantomjs as far as I know.

Thank you!

I looked at this, but this port is a "mess".

It uses it's own local copy of qt5, but without any of the qt5 enhancements that have been (extensively) worked on in MacPorts.

Unless it can be reconfigured to use MacPorts' copy of qt5, I'm afraid it might turn out to be a ton of work to make it go.

At any rate, for the OP, you can probably stop the rebuilding if you add this to the Portfile (wrong as it might be):

configure.cxx_stdlib libstdc++

and hope for the best...
