ERROR in rosmake tum_ardrone

edit

Hello, I am using the ROS Fuerte to build and launch the tum_ardrone package [1]. However, after building for sometime, the terminal returns an error.

[ 53%] Linking CXX executable ../bin/drone_stateestimation
Built target drone_gui
/usr/bin/ld: cannot find -lblas
/usr/bin/ld: cannot find -llapack
collect2: ld returned 1 exit status

What could be the problem here? Let me point out that the I downloaded the tum_ardrone git library instead of cloning it as my proxy would not allow a clone, but I feel it wouldn't matter. Thank you in advance!
How can I fix this?
