Installation of Mutt

[Sharon Blair]

I have installed Mutt on SCO Openserver 5.02.  When I try to execute
Mutt I get this error " dynamic linker : mutt : error opening
/usr/local/lib/libncurses.so.4  Killed".  I feel that I need something
else installed because this file doesn't exist.  Any clues or answers?
