[Cbc] [External] Re: 2.10 version on Ubuntu

[JP Fasano]

Ted,
Should the uninstall be done with sudo?

*sudo* ./coinbrew Cbc uninstall

If uninstall only removes the local files in the build directory, then
leaving out sudo should be OK,
but I suspect uninstall also removes the files in /usr/local which should
require sudo.

Thank you for doing all this work.
It is really helpful and appreciated.

JP
