Here's the error (just do "sudo port extract cmake-devel"; it results in this error on every OS I tested, from 10.5 to 10.14):
Error: Failed to extract cmake-devel: error renaming "/opt/local/var/macports/build/_opt_sources_MacPorts_ports_github_macports_devel_cmake/cmake-devel/work/cmake-772edffbf0c08fc0a6fcf74fb98545b7afcfee13-772edffbf0c08fc0a6fcf74fb98545b7afcfee13" to "/opt/local/var/macports/build/_opt_sources_MacPorts_ports_github_macports_devel_cmake/cmake-devel/work/cmake-772edffbf0c08fc0a6fcf74fb98545b7afcfee13/cmake-772edffbf0c08fc0a6fcf74fb98545b7afcfee13-772edffbf0c08fc0a6fcf74fb98545b7afcfee13": trying to rename a volume or move a directory into itself
