Hmm, what about use of the /usr/local hierarchy (eg. /usr/local/bin for the
dll) for install of the optimized version? A script in /etc/profile.d could
ensure that /usr/local/bin occurs ahead of /usr/bin in the path.
The fhs specifies /usr/local for local software installs that should not be
overwritten when updating system software.
