steps
sbt version: 1.3.4
problem
In some situations, SBT can be installed on a system which does not have the coreutils installed yet. The biggest example of this is when building relocatable RPM's and building an OS image in a chroot. When this occurs, the post install scripts attempts to use the rm command, which does not exist, and the script fails.
expectation
The SBT RPM should have coreutils as a dependency, even though on most systems it will already be installed.
notes
There is no Redhat-blessed way to force an ordering of non-dependent RPM's, so the only way that one can force coreutils to be installed before SBT is by changing SBT's dependencies.
