The questions below regard the osx dmg installer, not sure about how this applies to other installers.

I noticed that pyc and pyo files are included in the binaries. Is there a reason for this? I have removed them in the dmg for python3.1

Some reasons I can think of are reducing startup time, avoiding permissions issues for writing .pyc or .pyo files, and consistency (you're sure all installs have the same .pyo files).

Right but are they not recreated when the corresponding py file is accessed? So the speed to would only apply to the first run after install.

They won't be written unless the user has write permission in the directories where the py files reside, which is normally not the case when an installer is used, or any system-wide installation is done. Inclusion of .pyc and/or .pyo files is a standard part of the installation process for any platform. There is no advantage in trying to remove them. Eric

I see that f2py is installed in /usr/local/bin/. f2py is also located in versions/2.7/bin/ but I am not sure when it gets installed there (versions/2.7/bin/) and why id does not from the dmg installer. Any insight into this?

Should come from the installer right, where else can it come from? No idea at what point during install though.

What should the permissions be on the installed numpy files. When I install via $python3.1 setup.py install the owner = VMD(me) group=admin. To match the other dmg installs I have to run $sudo python3.1 setup.py install to get owner=root and group=admin

I am kind of working backwords. That is the numpy-1.5.1rc2-py3.1.2-python.org-macosx10.3.dmg was created by replacing the pkg installer file in the dmg from numpy/python2.7 with that from for numpy/python3.1 created with packagemaker gui. The packagemaker setup can be saved as a packagemaker document *.pmdoc which is just a collection of xml files. I can't find any python packages/scripts to edit/create .pmdoc files but that should be easy. Then I still need to have an automated script for the dmg (packagemaker only builds the installer) I have not looked for a python script for this but I assume bdist can be used as a guide (not sure about license issues) Are there better tools build dmgs using python?

Look at the numpy/tools/numpy-macosx-installer/new-create-dmg script and how it's called from the paver dmg task. If you have an mpkg that should work with very few changes.

Good point. I'll look at that.

I realize there is a lot I don't know about building binaries but I am interested so any advice on how to proceed or what the plans are for building py3 binaries would be appreciated and I will try to contribute.

Finally here is a py3 binary to try.

That works for me. The only small issue I can see is that the Finder window is huge when it opens, wider than my screen.

That is a feature :-) I guess I need to work on that a bit. It seems the dmg layout is not preserved when converting between read-write and compressed. Or I am otherwise somehow loosing the formatting from the original dmg. I need to look at the new-create-dmg and use that.
