Probably, but I don't know the details. The file Notes/nonroot.install
has what may be relevant guidance, but I'm not sure of that.

Correct - you have to set LD_LIBRARY_PATH or SHLIB_PATH. And programs
run by root won't pay any attention to these settings, so they will
fail! If that is unacceptable, you will need to run 'ldd' or the
equivalent to find out which libraries are used, and then create
symlinks in /usr/lib pointing to the Informix libraries -- in which
case, you don't need to set LD_LIBRARY_PATH or SHLIB_PATH for anyone.
However, you cannot so easily have two versions of Informix installed on
the same machine.
