Kicking this back to the list for closure.

Dear Alexander Hansen,

Thank you very much for your reply! I managed to resolve the problem,
but wanted to let you know and thank you for your help!

You were right that it was not an Octave issue at all, and I was finally
able to update all of the relevant ports through Macports.

Thanks!

Best,
Matt

        Hello,

        I do not know if this is the right mailing list to ask this, but
        I am
        horribly out of my depth, and would appreciate any help or
        re-direction
        that might be offered.

        So far, Octave has been working normally for the last month or
        so, as
        I'm learning very basic commands. However, in trying to use the
        function
        fminunc(), I receive the following error:

             dyld: lazy symbol binding failed: Symbol not found: _dlartg_

             Trace/BPT trap: 5
             logout
             [Process completed]

        A bit of unfortunate background: I am running OSX 10.8.3. I tried
        following the instructions for 'Manual Installation from
        Source', and
        was having difficulty getting Octave to build (probably should
        not have
        tried it, as I clearly didn't really know what I was doing). I
        think I
        tried to download and install Octave using Fink as well, but I
        do not
        remember, and somehow this did not work either.


    You didn't report that to me, sorry, or I could have helped you fix
    it :-)


    I finally succeeded in

        installing it using MacPorts, but I fear that my previous
        attempts may
        be part of what has caused some sort of library incompatibilities.

        Can anybody help me resolve whatever is causing this error, and 
what
        presumably will cause innumerably many errors in the future?

        Thanks so much! I really appreciate any help that you can offer!

        Sincerely,
        Matt




    Nothing here really to do with Octave.

    You might try using

    nm  /opt/local/lib/libtatlas.dylib

    to verify whether or not _dlartg_ is actually defined in that.  It's
    defined in Fink's build of ATLAS, so I can't imagine that it's
    missing from Macports' build.

    If, indeed, it is defined there, then the issue could be that you
    have DYLD_LIBRARY_PATH set, and it's pointing to a bad libtatlas.dylib.
