...but I was frustrated by this room. (Apparently graduate school has caused my spatial/Tetris skills to desert me.) And no one else seems to have had any trouble, since there's no Hints and Solutions thread on this topic.
How frustrated did I get?
See attached. (Sorry about the Very Ugly Code!) Since there are 46,809,527,353,344 possible combinations of upper-left X,Y coordinates for the pieces, I had to preselect, first by checking the 2,187 different combinations of Y-coordinate for overruns (which took a few moments to run), then the 1,337,720,832 combinations of X-coordinate (which took about 18 hours on one core of my desktop.) It boiled down to 62 x 1,236 = 76,632 possibilities, 0.000000164% of the original possibility space. Checking these for overlaps, in two dimensions, took about a minute.
Everybody else probably solved it just by looking at it. But DO YOU KNOW...

OK, one more secret room before the master wall comes down.
