Apache httpd 2.4.49 port will not launch on ElCap

[Bill Cole]

I've used the prebuilt binary and done a source build myself, it just won't launch.

A few startup messages are in the ErrorLog, but they don't note any reason for the crash.

The OS does manage to save crash reports when I try to start, all looking similar to the one below.

Googling about various specifics from the crash report (e.g. https://stackoverflow.com/questions/55286016/python-is-crashing-due-to-libdispatch-crashing-child-thread) makes me suspect that this has something to do with how httpd initializes itself. Telling bit is the "crashed on child side of fork pre-exec"

I'm wondering if anyone else has encountered this and if anyone has a sense of whether this is really a MacPorts-specific problem or if it is (as I suspect but have not been able to confirm) a problem with httpd.
