because your login shell is /bin/bash not /bin/sh (grep for your 
username in /etc/passwd)

The correct solution is not to use bash-specific functionality:

   `. whatever`

should work just fine. By doing this you'll help your script to be 
portable to other operating systems, like *BSD which tend not to install 
bash by default because of its restrictive GPL licence.
