A little more progress after I read Tutorial #9 for the fourth time is an
innocent sentence on page 2 that says "Stream files do not identify a
top-level cell, so you wont see anything on the screen after youve used the
calma read command. So, I saved all the cells with writeall and now I have a
myriad of .mag files in this directory like Inv, Inv2, Nand2, Nor2 and the
like. When I startup magic again on the invertor (magic -w -T
SCN5M_DEEP.12.TSMC) with say Inv.mag and run "drc find", I get about 34 drc
errors with what looks like some but not all features. So, I can actually
see a portion of the invertor from mosis, just not completely.

So, gds reads with some problems, and cif segfaults as of this morning.
