File not found errors building an RPM - python-2.7

Question

I recently inherited a build server that was running fine until last week and now I'm getting some "file not found" errors. I am using "rpmbuilder" as my non-root user. When I run my build command I get the following errors:
$ rpmbuild -bb -v rpmbuild/SPECS/mist.spec
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.fUrkkG
Executing(%install): /bin/sh -e /var/tmp/rpm-tmp.edkQrN
Processing files: mist-2.0.2-1.x86_64

RPM build errors:

I used to get a ton of output under %prep but now there's nothing. I tried using %setup without -q and still get the same output.
As far as I can tell my source files are still where they should be:
[rpmbuilder#coams-db SOURCES]$ pwd
/home/rpmbuilder/rpmbuild/SOURCES
[rpmbuilder#coams-db SOURCES]$ ls -la
total 66124
drwxr-xr-x. 3 rpmbuilder rpmbuilder 4096 Jun 23 10:08 .
drwxr-xr-x. 8 rpmbuilder rpmbuilder 4096 Feb 25 2016 ..
drwxrwxr-x. 8 rpmbuilder rpmbuilder 4096 Jun 23 10:08 mist-2.0.2
-rw-rw-r--. 1 rpmbuilder rpmbuilder 67681925 Jun 23 10:09 mist-2.0.2.tar.gz
Has anyone seen this issue before? Are there some nitpicky things I didn't know to check? Like I said I don't recall changing anything but who knows...
