This took some head-scratching but I eventually determined that it was the 
RPM for apr (rather than httpd itself) that needed to be rebuilt. I 
temporarily renamed /usr/include/sys/epoll.h on my Linux build host while 
building the RPM and that seems to have done the trick. With the tweaked apr 
RPM Apache can now serve requests from the jail.

I'm definitely getting closer. After some more testing I hope to write up the 
complete process for posterity. Stay tuned and thanks again for the 
pointers.
