Thanks Urs for your email. 

We had to slightly change ruby packaging to allow parallel installation
of ruby version for the future. Due to that, you need to rebuild your
pst* packages on SLE12 RC3 (no change should be needed on the specfile)
and they will install fine on RC3.

Sorry for this inconvenience but this is to ensure we are future proof
ruby-wise.
