To build the package, there is no need to run the configure script. Just use the standard cabal commands:

runhaskell Setup.lhs configure
runhaskell Setup.lhs build
runhaskell Setup.lhs install

The package uses a script to find what BLAS and LAPACK libraries to link with. To link with a custom BLAS or LAPACK, add the "--with-blas=" or "--with-lapack=" argument to --configure-option. For example,

runhaskell Setup.lhs configure --configure-option="--with-blas=<lib>"

To build this package from the git repository, first run aclocal -I m4 autoreconf
