The devel/tcllib tests create a lot of temp/scratch files. Currently this happens in `pwd`. Better to run the tests inside a specific directory.
The tests can be run in WRKBUILD but that requires adding SEPARATE_BUILD to a port that is already using NO_BUILD, which feels a bit silly. The tests can also be run in WRKSRC, which is fine, just a not as tidy. Same for devel/tklib. Thoughts/suggestions? Stu
