mention DYLD_LIBRARY_PATH in macosx installation instructions

[rburhum]

I've never had problems setting up a django environment on Linux or even Windows. However, I have always wrestled with getting it to work on a Mac and always ended up giving up and moving on. Turns out that all I needed was to setup the DYLD_LIBRARY_PATH in my .profile to get it to pick up the right libraries

export DYLD_LIBRARY_PATH=/Library/Frameworks/GEOS.framework/unix/lib:/Library/PostgreSQL/8.3/lib:/Library/Frameworks/GDAL.framework/Versions/Current/Libraries:/Library/Frameworks/GDAL.framework/Versions/Current/unix/lib:/Library/Frameworks/PROJ.framework/Versions/Current/unix/lib

Maybe someone should add it to the docs.

The documentation tries to stay away from giving too much detailed information about any specific OS/version/distribution. Instead, it defers and links to a wiki page in this wiki wiki:Distributions that can be modified by anybody.

It would be awesome if you can add the notes you propose to such page.

I'm not sure what happened in your specific case, but this is not generally true of Mac OS X. I've set up Django on numerous OS X machines running both 10.5 and 10.6 and have not needed to set this path variable.

Moreover, a quick search on Google returns quite a lot of advice saying *not* to set it the way you recommend, as it is likely to break other applications.

It may have been that things were installed in non-standard places... I've also heard reports of Fink or MacPorts misbehaving in the past, but I don't think it's safe to recommend this to everyone at present.
