MacPorts Snow Leopard Upgrade

with 18 comments

After upgrading to Snow Leopard using sudo port caused errors:

no suitable image found
no matching architecture in universal wrapper

I was able to fix the problem by installing the Snow Leopard compatible version of MacPorts found on the download page.

Once you’ve installed the new MacPorts  you’ll want to make sure the ports tree and base sources are the latest available:

sudo port selfupdate

Then I ran a command to recompile:

sudo port upgrade --force installed

dlopen(/opt/local/share/macports/Tcl/pextlib1.0/Pextlib.dylib, 10): no suitable image found. Did find:
/opt/local/share/macports/Tcl/pextlib1.0/Pextlib.dylib: no matching architecture in universal wrapper
while executing

  2. Yes, thank you very much.

    Also – I had to reinstall the developer tools from the Snow Leopard disk before macports would work.

    I kept getting the error:
    “… returned: can’t read “build.cmd”: Failed to locate ‘make’ in path: …”

    Once I reinstalled OS X Developer tools (Make sure you check the UNIX Developer tools checkbox), I was able to use macports again, and then I ran the above command and all worked as it should.

    Thanks a bunch!

  4. You need to install Apple’s Xcode Developer Tools and X11 per the instructions on the MacPorts download page.

  8. You saved my day as well. This was very useful. Thank you.

    At first I was reluctant to force an upgrade of all my installed ports but then I learned that MacPorts does not support migrating ports from one major OS version to another, so a rebuild is recommended anyway.

  9. I got errors when doing the sudo port upgrade –force installed

    so instead I followed these instructions:

    Basically uninstall all ports, then reinstall the ones I need one at a time.

  10. Thanks for the tip

  11. I know about those migraton instructions in the macports wiki. However, I have dozens of ports, and for me, it would take me a huge amount of time to figure out which ports to actually use and which order to specify them, as described in step 3 of that article.

    Does anyone know of an _automated_ way to auto-upgrade all of the existing ports when moving from the Leopard version of macports to the Snow Leopard version?

    I can’t believe that the only way to do this is to _manually_ figure out the list of appropriate ports and to _manually_ order them based on their dependencies.

    Thanks in advance.
