Linux does shared library dependencies properly, so libraries can declare
dependencies on other shared libraries themselves if linked properly.
Unfortunately, not all platforms are as kind.

Also, Linux applications usually don't actually need libnsl.  It's pretty
much just a NIS thing on Linux, unlike on Solaris where you need it to do
any basic DNS lookup.
