DG Compiler issue - Stand-alone lib, SOS.LB

Dear DG-Addicts, I am running RDOS (within simh) and I can readily compile and run Algol programs in this environment. Now want to compile Algol programs to be loaded stand-alone onto a 8k store machine via paper tape. To do this, a library called SOS.LB is needed (at least the linker complains, that it is missing) and so the question is whether some one out there has already compiled stand alone programs using RDOS and probably has the SOS.LB for Algol, and eventually further files required, available? I already tried to get in touch with people involved in these web sites http://www.chookfest.net/nova3/paper-tapes.html http://www.ludd.luth.se/~ragge/nova/swdocs.html but so far I have not got hands on the Algol stand alone stuff. BTW: I do NOT want to use the stand-alone tool chain, but generate the programs using the RDOS (because this is more convenient). Any hints are welcome, best regards, Erik.
