I had a small problem compiling cgminer (which I fortunately managed to overcome).
First attempt finished like this:
A search led me to this page (don't think it matches the problem exactly, but it did lead me to the solution).

and then it compiled fine.
Just thought I would pass this on in case someone runs into the same problem (or maybe this suggests an extra test in the build tools so that other users won't run into this problem).

Code:
LIBS = -lncurses -lpthread
