openshift-env-variables

I'm using a pre_start action hook to add some new paths to the PATH and LD_LIBRARY_PATH environment. after git push I can see that variables are updated, however when I ssh to the server, added variables are not available, after some googling I found out this is happening because these variables are exported as a sub-shell. openshift documentations suggest to add variables using set-env command, but when run it I get following error rhc set-env PATH=$OPENSHIFT_DATA_DIR/bin:$PATH" -a srv Setting environment variable(s) ... PATH cannot be overridden Does anybody know how we can overcome this? If
