The paint wasn't even dry on the last plab tarball before I have moved on...
Rev 20 of the tarball has no new function, it is just slimmed down. I replaced our large statically linked binaries with dynamically linked ones. Also found and stripped a couple of other binaries. The resulting tarball goes from 5.7MB to 0.9MB. The Makefile changes are to incorporate the NOSTATIC=1 environment hack to enable building the dynamic binaries above.
