Two little tricks that might help in the future.
One is tab completion--if you type the first few letters of a command, the shell will complete it. For example if I type py and hit the tab key (I don't know python, I'm afraid, so I don't have this program installed, but this is simply an example), I see
pydoc pylupdate pysol.bak pytovid
pygrub pymakemenu python pyuic
pygtk-codegen-2.0 pymakexml python2
pyidvid pysol python2.4
(this is on CentOS--your output, of course, might be different.)
So, if you've installed a program and aren't sure of its name, you can try typing some likely letters--in this case, had you typed pyu and then hit the tab key, you should have gotten pyuic4.
Another handy one, when you're trying to figure out how to get a program or package is
yum provides */<program_name>
For CentOS, it shows me that I need to install PyQt (and that, on CentOS, the program *is* called pyuic.)
(You might have to run this as root or with root privilege---I'm not sure if that's a CentOS thing or yum in general).
