The other option, which is what I did, and it seemed to work without problems.

Treat your local copy as a project in your favorite IDE.

Set up this project using the
address@hidden:/sources/ltib as the source.

Pull in changes and resolve conflicts.  There should be few as the cvs
versions of the base folder, bin, and config not from your platform
should be authoritative.  If package versions are in conflict these
can be resolved by overriding in platform/XXXXX/packages.lkc.
toolchain.lkc may need some work if they are using one not already
there. packages.lkc and pkg_map(-mx?) should be straight forward.


Getting your own ltib up-to-date will be big step forward in your own
maintenance of ltib as Freescale rarely updates the ltib in their bsps
and users are forever stuck in some ancient version.   It may even
provide some incentive for Freescale if you go back to them and show
them that you've brought part of their bsp up-to-date with the working
public version and they just may give the go ahead for releasing it
publicly.
