I must confess that I do not even begin to understand prebinding. Nor do I know what the OS X analog of the linux ldconfig command and configuration is. But I suspect that the answer to my problem will lie in those directions. I've installed gnome/gnucash using macports (that was a bit of a trick because of confusion about which guile installation was needed. Gnucash configure couldn't find guile16, but I had other problems with guile 1.8. I also needed to install "+without_docs" because otherwise port tried and failed to install firefox) But I did finally get something compiled and installed. However, it won't run, and this is what I get to standard error. dyld: Library not loaded: /usr/lib/libffi.dylib Referenced from: /System/Library/Frameworks/QuartzCore.framework/Versions/A/ QuartzCore Reason: Incompatible library version: QuartzCore requires version 1.0.0 or later, but libffi.dylib provides version 0.0.0 I note that there is a an /opt/local/lib/libffi.dylib installed, but apparently that's not the dynamic library that gnucash finds. As I've said, I am clueless about dynamic libraries, particularly on OS X. I'm running OS X 10.5.1 with Xcode 3.0 on a G5 PPC. I have also installed the update to X11 from Macosforge.
