Dang. I got the listener to start; I had overlooked copying tnslsnrO to tnslsnr. But same libskgxp8.so error from svrmgrl. I get it from sqlplus, too.
Neither of them are linking it in directly:
[oracle@abyssinian bin]$ ldd svrmgrl

I checked all of those libraries, and the ones they include, and I never found it. Things that make you go hmm.....
