mod_fcgid @2.3.6 shared-memory error when starting up

[macportscf@…]

I just installed the mod_fcgid port. As I loaded the module via LoadModule in Apache, the daemon refused to start. Instead it gave the error-message:

[emerg] (2)No such file or directory: mod_fcgid: Can't create shared memory for size 1192488 bytes

Setting pathes in the configuration didn't seem to help at all.

What I found is, that the patchfile of the port (patch-fcgid_conf.c) changes the default-path for mod_fcgid-related data (DEFAULT_REL_RUNTIMEDIR) from 'logs/' to 'var/run/'.

The problem is: this directory is not created by the port or by apache itself. When I manually created the directory apache started up just fine.
