#51417: mailman @2.1.22_0: ImportError: cannot import name C_ ----------------------+------------------- Reporter: gotow@… | Owner: mps@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: mailman | ----------------------+------------------- Comment (by gotow@…): Thank you for your comments. Clang is new for me. I re-installed MacPorts-2.3.4-10.8-MountainLion.pkg, and updated Xcode to the latest version. I used MacPorts and Xcode with default settings as installed. I tried to install mailman, and got an error message as follows. The main.log says that main compiler is clang 425.0.28 though not blacklisted in compiler_blacklist_versions-1.0.tcl. I used Xcode clang compiler without intentions. This might be the cause of an error as you pointed out. Could you please recommend the compiler that is suitable for mailman installation, and the way to use it? I attached the main.log for your reference. $ sudo port clean --all mailman Password: ---> Cleaning mailman $ sudo port install mailman ---> Computing dependencies for mailman ---> Fetching archive for mailman ---> Attempting to fetch mailman-2.1.22_0.darwin_12.x86_64.tbz2 from http://sea.us.packages.macports.org/macports/packages/mailman ---> Attempting to fetch mailman-2.1.22_0.darwin_12.x86_64.tbz2 from http://jog.id.packages.macports.org/macports/packages/mailman ---> Attempting to fetch mailman-2.1.22_0.darwin_12.x86_64.tbz2 from https://packages.macports.org/mailman ---> Fetching distfiles for mailman ---> Attempting to fetch mailman-2.1.22.tgz from http://jog.id.distfiles.macports.org/macports/distfiles/mailman ---> Verifying checksums for mailman ---> Extracting mailman ---> Applying patches to mailman ---> Configuring mailman ---> Building mailman ---> Staging mailman into destroot Error: org.macports.destroot for port mailman returned: command execution failed Please see the log file for port mailman for details: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_mail_mailman/mailman/main.log To report a bug, follow the instructions in the guide: http://guide.macports.org/#project.tickets Error: Processing of port mailman failed -- Ticket URL: <https://trac.macports.org/ticket/51417#comment:4> MacPorts <https://www.macports.org/> Ports system for OS X
