Try logging out then back in. I *believe* that when you type in a
command at the prompt, the system doesn't actually search each
directory of your path looking for the file. Instead, it looks at a
table in memory that was created when you logged in. If you install a
new program in those directories, it wont know about it until you
rebuild that table.
Honestly, I'm guessing at this - this would be one explanation for the
behavior I have witnessed. If somebody else knows better, please say
so. Also, if I'm guessing right, is there a command to reload that
data without logging out then back in?
