I want to report an apparently smooth upgrade of macports when I upgraded my OS to Sierra from Mavericks.
I tried to follow the instructions<https://trac.macports.org/wiki/Migration> exactly, and found some minor issues: 1) The lack of a gfortran meant that install errors were found using the restore_ports.tcl script. 2) I manually installed gcc49 which created gfortran (almost). 3) I had to manually softlink the commands “gcc” and “gfortran” to the versions found in /opt/local/bin. Then “gcc" and “gfortran" were on my path. 3) I tested it by installing Atlas first, which worked. 4) The restore_ports.tcl reported the error below. It does not seem to have propagated to anything else. Further testing of the ports will reveal if there are any issues. Instructions for installing command line tools of Xcode can be found here: http://railsapps.github.io/xcode-command-line-tools.html. Just issue the command xcode-select —install. Part of the install output: ---> Cleaning bzip2 ---> Fetching distfiles for cctools-headers ---> Verifying checksums for cctools-headers ---> Extracting cctools-headers ---> Configuring cctools-headers Error: cctools-headers has been replaced by libmacho-headers; please install that instead. Error: Failed to configure cctools-headers: obsolete port Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_cctools-headers/cctools-headers/main.log for details. ---> Cleaning cmsvlib Etc. Thanks to the community for an overall smooth and successful process. -- Tony
