There are a lot of details here.  It seems possible that the ncurses library
was built without a dependency upon the tinfo library.  (I do not have a
system with similar configuration to compare, so I am guessing).  On my
system, I can see the dependency in the library itself using objdump with
the "-p" option, e.g., the "NEEDED" lines in this listing:

libncurses.so.5.9:     file format elf64-x86-64
