That's because it skips the curses-based startup screen. If you
attempt to run any program which uses curses, you'll get the same
problem.

The error message is emitted either from the curses library itself, or
from a termcap/terminfo library which is used by the curses library. 
It almost certainly occurs somewhere within initscr() (i.e. between
the point that initscr() is called and the point that it returns; the
actual error will most likely be generated by a lower-level function).

The error basically indicates that the relevant library failed to find
a termcap/terminfo entry for "xterm".

If pre5 worked, your pre5 binaries were most likely linked against
different libraries. Either one is using termcap and the other
terminfo, or they both use terminfo but are looking in different
places (e.g. /usr/lib/terminfo vs /usr/share/terminfo).
