Steps to reproduce the issue

install of spack is as per documentation:

git clone -c feature.manyFiles=true https://github.com/spack/spack.git 
 . spack/share/spack/setup-env.sh 
more ~/.bash_profile 

Then I run installation of any software (tried gromacs and grace)

spack install grace 

I get the error:

==> Error: Spec version is not concrete: mkfontdir

I guess something is not right with the original instal of spack? But not sure how to check it.
Thank you!
