>=kde-misc/tork-0.13 is masked because it depends on net-misc/tor-0.1.2.3, which I think should be >=net-misc/tor-0.1.2.3. net-misc/tor-0.1.2.13 is in the tree as unstable and therefore >=kde-misc/tork-0.13 can be unmasked as unstable. Reproducible: Always Steps to Reproduce:
I have unmasked tork and bumped it to 0.17. Have fun! :-)
