## Set LD_LIBRARY_PATH
##
## On Solaris we use $ORIGIN (set in RUNPATH) instead of LD_LIBRARY_PATH 
## to locate shared libraries. 
##
## When a shared library is a symbolic link, $ORIGIN will be replaced with
## the real path (i.e., what the symbolic link points to) by the runtime
## linker.  For example, if dist/bin/libmozjs.so is a symbolic link to
## js/src/libmozjs.so, $ORIGIN will be "js/src" instead of "dist/bin".
## So the runtime linker will use "js/src" NOT "dist/bin" to locate the
## other shared libraries that libmozjs.so depends on.  This only happens
## when a user (developer) tries to start firefox, thunderbird, or seamonkey
## under dist/bin. To solve the problem, we should rely on LD_LIBRARY_PATH
## to locate shared libraries.
##
## Note: 
##  We choose libmozjs.so as a representative shared library. If it is 
##  a symbolic link, all other shared libraries are symbolic links also.
