When Sun introduced LD_LIBRARY_PATH in its operating systems (later
adopted by Linux) it was described as a tool for use by developers
rather than end-users.  For Solaris, I prefer -R, but Linux and
FreeBSD users will likely prefer to do without.  They may use some
other means (e.g. ldconfig or LD_LIBRARY_PATH) to configure the
library search path.

This is a topic of never-ending debate.

As a result, for packages I support, I provide supporting
documentation and expect the users to do what they want.
