My first challenge is getting back to the 64 bit python. (By the way, is there a way to tell, once I have it, whether it is 32 bit or 64 bit?) I guess import sys; print sys.maxint should tell you. It will return 9223372036854775807 for 64 bit and 2147483647 for 32 bit. Macport sounds like a WONDERFUL idea! I agree its a good idea, but is it a good solution in practice? There may be downsides to using macports, for example if you have to install something from source that has depends on other packages which you installed with macports, will you know how to proceed? When I first started using mac about month ago I asked on this mailing list about good practices and at one point the conversation turned into a discussion on the merits of Fink and macports. Someone suggested I try to do things The Mac Way for a while before embracing Fink or Macports. I think that was good advice, I learned and tried to make people aware of what I perceived to be important pitfalls and workarounds. I also learned that what I missed most, having come from gentoo linux, was the package manager that helps me keep all of the open-source software I use up to date. I noticed your comments were prefaced with if you are not using macports... I have just installed it, but want to do some sanity checks before I start trashing my system. I did a SEARCH and found Python26 - but there is no reference to it being 32 or 64 bit - how do I know it is the 'right' (64 bit) one? check sys.maxint. If I understand your notes below, I should macport qt4-mac-devel because the qt4-mac is actually 4.5.3 and the one I really want is 4.6.0? I think py26-pyqt4 depends on the qt4-mac port, which I could not get to build (probably because I have plenty of cores on my machine, and it does a parallel build which can sometimes lead to missing symbols errors in my experience with gentoo.) So you can't just port install qt4-mac-devel py26-pyqt4, you have to copy the qt4-mac-devel directory from the macports repository and save it in your local repository as qt4-mac (don't forget to change the name in the Portfile). See the macports documentation for details on how to deal with local repositories. I notice that there is also a py26-sip that macport found - I assume that is the right one to install after python. Yes, but I think port install py26-pyqt4 will pull that in for you. I also found a macport for py26-pyqt4. Will macport'ing this complete the installation? (i.e. replace the instructions you gave below?) It should. Sorry to ask so many dumb questions, but the environment is still a bit alien to me. It's ok, but lets try not to spam the list with discussion about OS X and macports if it is not directly related to PyQt.

Re: [PyQt] Need help installing PyQt on Snow Leopard
After switching my OS X Snow Leopard python default to 64-bit with: defaults write com.apple.versioner.python Prefer-32-Bit -bool no And then following Darren's directions, everything went fine until PyQt make install, which proceeded without problem until ld: library not found for -lqpygui collect2: ld returned 1 exit status Googling for lqpygui was not helpful so wondering if anyone has any thoughts.

Never mind. I switched to the current snapshots and now everything's working fine. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
