You may have created yourself problems. brltty is installed by default
in Ubuntu.

In an Ubuntu default installation, it should be enough to go to the menu
System -> Universal Access and change the Assistive Technology
Preferences (at least this is how it is called in the preview version
for Ubuntu 7.10)

As I said, it is installed by default and the package set up the links
by iself

You don't need to do that in this case, but read the links and man page
I gave for how to do it in principle

Go to menu System -> Help, and then search for "braille". It will show
you documentation on how to set it up.

Before you do anything, you should undo all the manual changes you have
needlessly done, and reinstall Ubuntu's brltty (you can do so from the
Synaptic package manager)
