/usr/local/lib is usually on the linker's default path, so any library that you
put there should be picked up automatically. On Ubuntu, this is not the case so
that's why you have to add it to the linker path using the LD_LIBRARY_PATH
variable. Another way to do it is to edit /etc/ld.so.conf or some file in
/etc/ld.so.conf.d -- this will add /usr/local/lib to the linker path
permanently, for all users of the system. See the following question on
Stack Overflow:

http://stackoverflow.com/questions/17889799/libraries-in-usr-local-lib-not-found

So yes, I think this issue is related to Ubuntu systems only, but as it is
a fairly common Linux distribution, I think it's worth adding a note to the
homepage.

All the best,
