Do as you like. ;-) Generally speaking I don't like setting
LD_LIBRARY_PATH (or even LD_PRELOAD) globally (t.i. session-wide)
because I have seen many applications that fiddle with the
LD_LIBRARY_PATH themselves and are not prepared for the variable
already being set. So they either break that functionality or fail
with weird errors. If you explicitly called such an application with a
wrapper you are aware that you did just that and can easily try the
application without the wrapper. Global variables tend to be
forgotten...
