As of Solaris 8 and later this is no longer true. crle lets you
configure the runtime linking enviroment. You can use this instead of
hacks involving LD_* to work around when you cannot re-link a program,
but it's still recommended to use -R to provide the correct library
search locations.

"The evil hack way", and you probably meant LD_LIBRARY_PATH, not
LD_RUN_PATH.

Which is what I suggested earlier.

Not really, I build them all the time with no problems. I have a good
site.def so xmkmf things Just Work, otherwise it's a few more -R
settings.
