Well, RedHat's bugzilla has a bug stating that ldconfig isn't run
automagically even tho it ought to be, which explains why my system
doesn't do it.

Thinking back, which was looking through a bigger chunk of the box cause
my personal account had a longer PATH (frex, I remember /, /usr/bin,
/usr/games and /sbin being in my account's path. this is a new distro
for me, and my default PATH is a lot shorter, and root's is positively
paranoid compared to mine).

I'll check it out... I lose stuff quite regularly.

Nope, I was thinking of which and forgetting that I had a bigger path
using my old distro. Whereis sounds pretty useful too tho. 

I'm thinking of making up a list of things I wish I'd known before I
started using Linux and Unix. Some of them are pretty silly (like chmod
is cool because it lets you fix permissions when your distribution
installs a copy of a game whose the top level directory is not
executable) and others are a bit more serious (like apropos is cool
because it helps you figure out what else to look at when you're stuck
on a tricky problem).

Emily, who is happy because she now has a copy of Windowmaker that works
the way it is supposed to and will let her play gnomehack and use
