I tried reinstalling with no luck.
I think the exception and stack trace are secondary to the main
problem, which is described by the two messages in the error_log:
(88)Function not implemented: AH00023: Couldn't create the proxy mutex
(88)Function not implemented: AH02478: failed to create proxy mutex
The exception goes away if I remove mod_perl from the configuration,
but the errors and failure to configure are the same. I also tried
launching httpd in a mintty shell that was started with administrator
privilege level, but the same error occurs.
The "Function not implemented" seems to indicate something mis-matched
in my system but I cannot figure out what.
