The build of the latest version seems to hang in tests: /usr/bin/tclsh8.4 ./tests/all.tcl reportedly in nice.test.
A large number of the tests in the tests subdirectory fail or hang. chroot, nice, pipe, and so on. I patched a few, but ran in to more failures. The test suite seems sort of abandoned, so I've disabled 'make test' for now in the RPM. If we can get a better replacement for 'make test', I'll turn it back on.
