Re: (not-debian-)programs not finding libraries on Debian system...

Taking this to debian-user, as suggested.

Sid. Come to think of it, there were a number of programs I compiled,
this wasn't one of them... these binaries are precompiled. So it wasn't
compiled on my system. Does this make a big difference?

xlib6 is not installed... I can try that, but all the libraries it
complained about was in /usr/X11R6/lib/, one for one I made symlinks in
/usr/lib, and it got past each of those then ... after the 7th symlink I
decided, no, I'm polluting my system, there must be a cleaner way.

There is an ld.so.cache. Not an ld.so.preload. (the strace shows this if
I am reading it correctly.) I reran ldconfig, but that didn't help.
