perhaps the former.

The makefile (unless something in the environment confuses it) would
have the -I and -L options first in the command-line, to persuade
the compiler and linker to use the in-tree sources/objects.

However, if you're configuring shared libraries, for some platforms
those options aren't enough.  I haven't done anything with HPE NonStop,
but recall some versions of HP-UX having shared libraries effectively
building into the library the install-directory's path (and ignoring
easy workarounds such as environment variables).

So... your build might be trying to link against the system's curses
library (which might have some different symbol such as "_attron").
