Re: sage only runs as root

[Volker Braun]

I would guess that the permissions of the dylib files or the containing directory are wrong.

Even things like 2+3 do not work. However, when I invoke sage as "sudo sage", everything works perfectly. What's wrong?

It appears that this is a flawed installation. We'd need a bit more information to be sure we're giving you the right help:
- OS/version (e.g. Mac OS X, 10.6.8)
- Hardware, CPU (e.g, MacBook Pro, Core i7)

One thing that is odd is that your installation is relying on libs in "/opt" (indicating MacPorts is installed). This is the problem, I think. Did you download a binary or build from source?

MacPorts is indeed installed, I installed sage from binary.

Oh, yuck. Looks like the binary was built on a system with MacPorts installed, which renders it kind of useless, I think.

From this outcome:

recovery may be as simple as making a symlink from /usr/lib/libiconv.2.dylib to /opt/local/lib/libiconv.2.dylib.

if that doesn't work, you could build from source. You'll need Xcode 4.2/3 installed to do this. Or wait until someone builds a good Mac OS X binary.

Perhaps sage-devel should know about this - I've CC'd them.

What version of Sage is this? Which binary in particular did you download?
