Resolving dependencies...
cabal: Could not resolve dependencies:
trying: blas-carray-0.0.1 (user goal)
next goal: blas-ffi (dependency of blas-carray-0.0.1)
rejecting: blas-ffi-0.0.1, blas-ffi-0.0 (conflict: requires pkg-config package
blas-any, not found in the pkg-config database)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: blas-carray, blas-ffi
