[ptxdist] [PATCH] zlib: Fix build on non-Linux hosts

[Bernhard Walle]

The build system of zlib uses 'uname' to determine the operating system
for which it compiles zlib. However, on non-Linux hosts, this leads to
wrong results.

Fixes Darwin (tested on Mac OS 10.7 Lion), doesn't break Linux (verified
with current Arch Linux on x86_64).

I think that one is okay but just got lost, right?

[ptxdist] How to deal with alternatives

[Erwin Rol]

Hey all,

I was wondering how I can deal with alternatives packages?
I have a nVidia BLOB driver for Tegra 2 OpenGL ES. That drivers brings 
the OpenGL libs that are needed by 3d programs. But those programs all 
select MESALIB which brings the opensource OpenGL libraries.


So how can I deal with two (or more) packages that offer feature XYZ 
that is needed by other packages?
