You may also want to modify /etc/environment, so that programs
other than Bash get the new PATH as well.

(Your system may call /etc/environment something else.  Look in
/etc/pam.d/login or /etc/security.d/login for pam_env.so for
some ideas)

In general, it depends on the program.  man, though, usually looks
in /etc/manpath.conf. (man 5 manpath)

That might be necessary.  If you're lucky, though, you might be able
to get away with adding the new location of /usr/lib to /etc/ld.so.conf
and the environbment variable LD_LIBRARY_PATH (same syntax as
$PATH).

Your life will almost certainly be drastically easier if you
create a symlink from /usr/lib to the new location...
