Here's a couple ebuilds I whipped up for TADS 2.5.8 and 3.0.7. They're slotted, but the source all comes from the same package. Tested successfully on my system.

Bug 149764 is an ebuild for a more current curses interpreter - FrobTADS. cheers
Bug 149764 is not only a more current interpreter, but is the successor to this one. Development on this one has stopped and the package is obsolete. It should not be included in portage.
Someone please close this ancient bug? TADS has been in portage for a while now (games-engines/frobtads).
