Welcome - everything is fine, but if you could please restrict your
line length to some 70 characters or so?

eldk-switch.sh (or any other script or program) cannot modify the
caller's environment, i. e. here the environment of the shell where
you run the script. You must use an "eval" command to do that, as it
is documented in
http://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.8.3.
Please see especially this section:
Then define the following shell function:
eldk-switch ()
{
eval `eldk-switch.sh $*`
}
Note: It is a good idea to add this definition to your
~/.bash_profile file, so you always have it ready available.
Then use the "eldk-switch" function instead of eldk-switch.sh, and
everything should work as expected...
Best regards,
Wolfgang Denk
