&gt; &gt; I have something that runs now and I'd like to clean up my work<BR>
&gt; &gt; and put some of it in good shape for submission.<BR>
&gt; &gt;<BR>
&gt; &gt; I was working on x86-macos with 10.5 and a friend of mine was<BR>
&gt; &gt; testing on x64-macos with 10.6 (he also have a ppc-macos, presumably<BR>
&gt; &gt; 10.4 on which he plans to test the stuff).<BR>

&gt; &gt; 1) I have one ebuild in which I need to set<BR>
&gt; &gt; How do I identify the various flavours of OS X, 10.4, 10.5, 10.6, to set<BR>
&gt; &gt; it right?<BR>
&gt; I'd like to trace down why your package needs this to be set.&nbsp; The<BR>
&gt; Prefix profiles for OSX already set MACOSX_DEPLOYMENT_TARGET explicitly<BR>
&gt; to the right version.&nbsp; Check make.defaults and profile.bashrc.<BR>
I didn't know this at the time I wrote my message. It is indeed set just fine<BR>
by the system.<BR>
&gt; &gt; 2) framework: I noticed that we build the python framework. Do we<BR>
&gt; &gt; preferably build framework? Or the reverse? I have worked on dev-lang/R<BR>
&gt; &gt; and I didn't build it as a framework and ended up with a bunch of .so<BR>
&gt; &gt; which should have been &quot;.bundle&quot; I believe.<BR>
&gt; We build the framework *next* to the normal UNIX way, just because of<BR>
&gt; graphical application support for Python.&nbsp; Due to how OSX works, a<BR>
&gt; graphical application that uses CoreGraphics (or something) needs to<BR>
&gt; call those methods from a Bundle environment, which a Framework is.<BR>
&gt; It is preferred not to build in frameworks in Gentoo Prefix from my<BR>
&gt; point of view where possible.&nbsp; Note that Python is built in both ways,<BR>
&gt; such that you only need to worry about the Framework when you do a<BR>
&gt; graphical app (which in general only looks for the Framework, so that<BR>
&gt; works out nicely).<BR>
&gt; The .so vs .bundle is an a problem sometimes solved using elibtoolize,<BR>
&gt; but in R's case probably by patching the buildsystem.<BR>
Ok, I tried to build the framework for R but the install routine to install<BR>
the framework is just awful.<BR>
