Wow, your advice is very helpful and generous.
I uninstalled manually.
I also started over with a fresh copy of the source code but when i fixed
the bug as described in unix.cpp. My make fails.
Starting failure is at the unix function XDisplay not present.

I  may try again though. I did manage however to uninstall manually as you
suggested. Then i went back to the original non source version and
installed that. I am back to where i started from which in my case, is
progress :)

Thanks for the advice.
