Dear Bernhard,

First of all thanks for the great work on porting ptxdist to mac! Since 2010 I tried using it from time to time on my mac, but alway went back to our Linux compute servers for one reason or an other.

I'm using a "quiet modified" version of 10.6 (python27, ncurses, coreutils, git, and several others form macports). So my system is probably not a reference system at all. But 

So, following your your document I end up with a working tool-chain, a working qemu-arm-softmmu and a working kernel, but no hdd img.
I had to fix 
.../lib/ptxdist-2012.04.0/scripts/genhdimg
replacing seq by gseq. But the better approach may be a symlink in .../lib/ptxdist-2012.04.0/bin/

The next point is concerning the files system on a Mac. AFAIR the default filesystem is the case insensitive version of HFS+ (this is definitely true up to 10.6). So the OSELAS tool-chain rejects to build. And further on some of the packages will also fail. Obvious, there are two solutions. Using an external disk with a case sensitive file system (e.g. HFSX, ext*) ore using a (sparse) image as a container. I decided to use the latter approach.

The last point I tumbled over is the git command on page 10:
% git am git clone git://git.qemu.org/qemu.git
Whats the purpose of this command? Is it really needed?

An other thing is xargs ... without the gnu version make distclean fails. The solution is to symlink in .../lib/ptxdist-2012.04.0/bin/, too.

Finally I added two patches to reflect these changes. May be the second patch (Makefile.in) still needs some work to be in its final state. I am not sure, in which make targets the

Subject: [PATCH 1/2] check for GNU seq and GNU xargs

On Mac OS X 10.6 seq is not available by default. And MacPorts creates
no symlink to /opt/local/bin.
BSD xargs does not accept the '-r' option.

Subject: [PATCH 2/2] Use tools as identified by configure

The configure script checks for several (GNU) tools to exist and saves
their PATH. Thus the Makefile should use the saved PATH as well.
