First, check how Bash is linked: "readelf -l /bin/bash | grep
interpret". Of course, this should say that it's looking for the dynamic
linker in /lib. Then verify you actually have all the right libraries
for Ncurses: "ls -la {/usr,}/lib/*ncurses*"
You could also just upload your build scripts for Ncurses, Readline, and
Bash.
