I have to admit that I don't know what "configuration items" are -
but I can report that the simple approach of copying libmx.A.dyso
from a 10.4 system to a directory which I added to DYLD_LIBRARY_PATH
seems to work
on the 10.3.9 PPC machine for the first tests I ran so far.

(disclaimer: as I said I don't even use "long double" so I did not
test this of course)
