[Pythonmac-SIG] Can't build PIL on Snow Leopard

Does anyone have a PIL binary for Python2.6.4? That would be the easiest 
way to get it?

I built one for Frederik last spring, but I don't know what happened to 
it, nor do I remember whether it was for py2.5 or py2.6

It's not too hard to do -- at least with 10.5 machine -- I have a 
10.4.11 PP now, and macports does not build Universal right at this 
point :-(

That is likely. If you look at the error messages that came before, you 
may find more details, but PIL does depend in a couple other libs that 
Apple does not provide.

You will find a list of these libs in the PIL docs, and probably 
discussion about Mac-specific issue in the archives of this list and 
assorted Wikis  -- do some goggling. I think you need libjpeg and 
libfreetype, though freetype may now come with OS-X 10.6

The easiest way to get them is to use macports (or maybe fink).

If you just need it to work for you, then it's pretty easy. Use macports 
to build libjpeg, and make sure the PIL build can find it, and away you go.

If you want to re-distribute, then you'll want to build the libd 
Universal, which macports shoudl be able to do with:

port install libjpeg _universal

or something like that. Then you want make sure that PIL finds only the 
static libs -- I think macports builds both, so you may need to go 
delete the *.dylib versions so that they won't be found -- a kludge, but 
gcc really tries hard to use dynamic libs.

Sorry I don't have time to do more right now!
