Mac OS X
This is a Mac OS X diskimage kindly provided by Dan Colish. It is suitable for Intel Macs (i.e. all vaguely new models - see Apple's site for how to check), and was built on OS X 10.6.8, so requires 10.6 or newer (10.5 and earlier are no longer supported by Apple, so hopefully this isn't too much of a limitation).
If you want to build it yourself, you'll need to make sure you have
Apple's Xcode installed
(which costs nothing), then download the Survex source code, unpack it and
tar zxf survex-1.2.15.tar.gz cd survex-1.2.15 ./buildmacosx.sh
If you want to build for PowerPC Macs, you'll need to edit buildmacosx.sh - search for i386 and read the comments around there.
