You should use the 'system' procedure to run shell commands. Like so:

build {
    system "cd ${worksrcpath} && ./Configure -build -d -f config.sh"
}

destroot {
    system "cd ${worksrcpath} && ./Configure -install" }
}

You could also achieve the same effect by setting build.cmd, build.args,
build.target, etc. as needed, but this is so different to a standard
autotools build that that is probably the messier route.
