Redmine

Hello,

One of my redmine installations stopped working after a service restart.
Could not find any plausible cause so after a day I decided to start from scratch.
Installed redmine 2.6.9_2 from package, did the usual configuration for database and local gems and ran bundle install
So far no problems.
But when running 'rake db:migrate RAILS_ENV=production' I got the error:

LoadError: Expected /usr/local/www/redmine/app/models/version.rb to define VERSION

I would like to add the output of script/about, but that gave me the same error.
Overall:
System = FreeBSD my-devel 10.3-RELEASE-p2 FreeBSD 10.3-RELEASE-p2 #0: Wed May 4 06:03:51 UTC 2016 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64
Ruby = ruby 2.1.8p440 (2015-12-16 revision 53160) [amd64-freebsd10]
Database = mysql 5.6.30
WS = thin 1.6.4 codename Gob Bluth

Clean install, so no plugins installed. Connection to database with configured user/pass works fine.
webserver log is empty

I compared every single bit I could think of with other installations that work fine.
Can't find anything that would indicate it is the culprit.

Thanks in advance.
