 ## 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/libxul.so is a symbolic link to
 ## toolkit/library/libxul.so, $ORIGIN will be "toolkit/library" instead of "dist/bin".
 ## So the runtime linker will use "toolkit/library" NOT "dist/bin" to locate the
 ## other shared libraries that libxul.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 test $MOZ_DIST_BIN/*.so. If any of them is a symbolic link,
 ##  we need to set LD_LIBRARY_PATH.
