You can see that the associated call/failure is happening inside APR
here, on

The issue is that if the library is configured (at build time) to
USE_GETRANDOM, then it assumes that the getrandom() call will be
available and
if it fails it becomes a fatal error. On my system, I don't have getrandom()
because I'm running an ancient kernel, but others could (more legitimately)
have the option disabled on a recent custom-built kernel.
I think the correct fix is to not use that build-time option, and go back to
using DEV_RANDOM or whatever was being used previously. Alternatively, at
least document that a kernel with getrandom() support is required to use
apache2.
I'm not sure exactly when the packaging on this changed, but I know it was
broken in 2.4.46-1 and I *think* it worked in 2.4.43-1, although I can't
get a
copy of that to double-check anymore.
