Hi all,

I have been toying with a Gentoo prefix on OS X (10.5) for the 
last month. 

I spent most of my time getting things in shape to have sage from
the sage-on-gentoo overlay build on OS X.

I have something that runs now and I'd like to clean up my work
and put some of it in good shape for submission.

I was working on x86-macos with 10.5 and a friend of mine was 
testing on x64-macos with 10.6 (he also have a ppc-macos, presumably
10.4 on which he plans to test the stuff).

1) I have one ebuild in which I need to set 
MACOSX_DEPLOYMENT_TARGET
How do I identify the various flavours of OS X, 10.4, 10.5, 10.6, to set
it right?

2) framework: I noticed that we build the python framework. Do we preferably 
build framework? Or the reverse? I have worked on dev-lang/R and I didn't 
build it as a framework and ended up with a bunch of .so which should have 
been ".bundle" I believe.

3) how do you do debugging? I installed gdb-apple and build stuff with
-ggdb and nostripe, but gdb still says it cannot find the symbols...

Cheers,
Francois
