Sorry for the confusion. ~/.bash_profile is not the problem here. I
have the following line in /path/programtorun.sh

. ~/.bashrc

In ~/.bashrc, I have ". ~/bash_some". In ~/.bash_some, I have some
variable assignment VAR=blah.

However, VAR is not seen in env in /path/programtorun.sh (called from cron).
