It looks like monkey.org is unreachable, so I changed build.sh c_dependency -m "0b3ea18c634072d12b3c1ee734263664" \ "libevent" "${le}" \ "http://monkey.org/~provos/${le}.tar.gz"; To c_dependency -m "0b3ea18c634072d12b3c1ee734263664" \ "libevent" "${le}" \ "http://httpsqs.googlecode.com/files/${le}.tar.gz"; That worked for me.
