Alternatively to using LD_LIBRARY_PATH it's also possible to use ELF
RPATH to hold the library paths.  For instance, adding the following to
the compiling command using GCC would
add /home/eschulte/Desktop/lisp-lib:

-Wl,-R/home/eschulte/Desktop/lisp-lib

objdump -p	from binutils should show the RPATH entries for an ELF object
ldd		depending on your OS, should display the library dependencies and
		the fullpath found to them

Your custom RPATH directives can be added to C:*USER-LD-FLAGS*, which
ECL will use when generating the compiler commands.
