LD_LIBRARY_PATH is just plain evil.
However, it does allow me to do oddball things like getting rdesktop from
Blastwave running on BeleniX :

But in general "LD_LIBRARY_PATH is just plain evil".

So then a dream would be to get a single base set of libraries that work
for all the apps on top. Regardless of what the app is or where it is
parked it can depend on a base lib in /opt/foo or /usr/local/lib or
whereever. Gee, maybe drop the common base libs into /opt/foo and then
create links in /usr/lib that point there. Nope, that won't work. I boot
exploding due to /opt not being mounted yet.
So the dream is still a common set of libs that are up to date and able to
be compiled and dropped ( repeatedly and consistently ) into some LIBPATH
somewhere on Solaris 8 and upwards.
Oh .. I posted this to companion-discuss at opensolaris.org .. probably bad
etiquette on my part but I really want to comply with the community
decision to get the discussion there. Hard to believe but true.
