initdb of pg 9.0.13 fails on pg_authid

I'm having some trouble installing `9.0.13`.

Compiling worked just fine. (The only flags used were `--prefix=/opt/pg9013
--with-perl`).

However after running bin/initdb, it fails:

The md5sum of my tarball checks out. This was built w/ GCC-4.8.0 on an
x86_64 Linux kernel.

Any ideas why this might fail? Thanks!
