You can't put $ signs in IDL programs, only use it from the command line.

You are already using single quotes in the sed command. You can't just blindly but 'the above text' in single quotes because then it becomes
SPAWN, 'sed -i 's/jumbledymuck/g' progo_dark_limb0.pro'
and the s/jumbledymuck/ portion is no longer quoted at all. Use
SPAWN, "the above text"
with double quotes instead. It gets really fun (in a bad way) if your Unix command has both types of quotation marks.
