I don't think their license is an obstacle to making a package. The
gist of the license is 1) "We're not responsible", and 2) "The license
has to stay with any derivative work". Only a heavy-hitter like AT&T
would feel the need to to assert that they can't be sued for bugs in
free software -- for everybody else, that goes without saying. The
license is generally more liberal than the GPL; there's no requirement
to redistribute the source with the derivative work, just the license.

The suite builds out-of-the-box easily. I looked at making a package,
but gave up, as

  1) It doesn't look easy to build *just* ksh, and the entire suite
     duplicates a lot of functionality in the base system (and if you
     want the entire suite, you could just follow AT&T's directions to
     build and install it.)

  2) I really didn't like ksh93 -- I like pdksh better. Sorry. :-)

If you just want to try ksh93, you could certainly download the whole
package and follow the directions. I also doubt that anyone would
strongly object to having a NetBSD package for it, if you want to
create one, but you could ask on tech-pkg.
