You might get such errors when one of liblapack's dependency is not
available as a static library. What is the output of `ldd
/usr/lib/liblapack.a'? The solution might be as simple as installing
development packages for these dependencies, or might involve
recompiling them for use with -static (i.e. into .a instead of .so).


Hope this helps,
