[sudo-users] Sudo on AIX 6.1

[David Flatley]

   Getting the following failure when compiling Sudo on an AIX 6.1 TL6 PPC
system.
Ran the same script to compile on a 5.3 TL7 system with no issues.

Checking POSIX...no
configure: error: Must have POSIX termios to build sudo
make; make 1254-025 There must be an existing description file or specify a
target
make: 1254-002 Can not find a rule to create target install from
dependencies

   Thanks
