I checked all the modules for libapr/libaprutil usage via
'ldd *.so | grep apr' and found no hits. I know that the error
contants are in a header file and not the library. Do the modules
use the APR constants without actually using the libraries?

For what it's worth, I've created the new httpd RPM with the modified
mmn. My limited testing (SSL, PHP) hasn't blown up in my face yet.
