make a small test program, that uses pthread_cancel and try to compile and 
link it.

or you could find out with strings if that function is in there.

lastly, i see you're building the .a file. don't do it and make it dynamic, 
that could also have been an issue. if not at least it'll make the problem 
alot more visible
