when emerging dev-python/twisted-2.0.1 with the test feature set in portage, it fails, saying the message below. I tried it with /dev/tty set to root:root crw-r----- and crw-rw----. before, it was set to loes:tty crw-r-----, which also caused it to fail. loes is just a random user on the system.

Reopen if you can reproduce this w/ >=2.4.0
when invoking python myself as root, this works fine: >>> f = open("/dev/tty", "r+") >>> f <open file '/dev/tty', mode 'r+' at 0xb7c48380> also, portage drops root privileges during the compilation, so porbably also during the testing (userpriv feature). the portage user doesn't belong to the tty group, that may be why it fails...
2.4.0 still seems so far away (Available versions: 1.2.0 ~1.3.0 2.0.1 ~2.1.0 ~2.2.0 ~2.4.0 ~2.5.0) but when chmodding /dev/ty to a+rw, the test passes and twisted merges just fine. I think the testcase should be skipped whe /dev/tty can't be opened, instead of fail. other tests, like the database connector tests, are marked skipped as wll when the database can't be connected to.
