I ran into a couple more issues after modifying this. I'm not sure precisely how to resolve the discrepancy between the installation instructions and what it actually takes, so I'm just pasting notes here.

1. After downloading, unzipping and building the hiredis-master project, you'll find that no .a file is created from the default build.
2. In addition, I had to do a "make static" to build the libhiredis.a file.

Rebuilding and reinstalling led to apachectl graceful allowing restart without complaint.

Tests failed, but that appears to be for factors external to the project.

One of the things I overlooked was making sure I was running against httpd 2.4. After upgrading to 2.4, my tests are able to complete properly, but in the interim I also ended up downgrading hiredis to version 0.11.0, which I can confirm works with mod_redis.

At this stage, I'm going to retest with the latest version of hiredis and will update here when I'm done.
