Re: [gentoo-alt] Problems with getting gentoo scientific packages installed

Hi JC,

You can add per-package accept keywords to particular packages in the same manner as per-package use flags:
1. mkdir $EPREFIX/etc/portage/package.accept_keywords
2. create files in there with per-atom definitions like this:
=app-text/dos2unix-6.0.6 **

3. Now if you try to emerge the package it will ignore the keyword restrictions and try to install it anyways.

Alternatively you can setup an overlay, copy the existing ebuilds into it and modify them so that they work under OS X.

Hi Jeremy,

Yes it helps ;-)
I checked Macports and found that all my favourite packages are available there. For productivity reasons I have to think about using macports again or give homebrew a try.

The installation problems are mostly related to some basic packages such as lisp packages sbcl and gcl.
It wasn't even possible to install emacs.
However, if helps to improve gentoo_prefix I will go on ;-)

Could please tell me where exactly I  have to add the keyword? "(just add the keyword and it will work)"
You mean in my make.conf? Or how where do I have to add so it will be applied to a certain package.

Thank you!

There is probably no problem with your Gentoo Prefix installation. It
looks like you are trying to install some packages that have never
been tested and/or ported to to x64-macos architecture. You will have
various levels of success here, ranging from easy (just add the
keyword and it will work) to very difficult (rewrite the poorly
written scientific package build system to support an offset). At
least, if the package exists in Macports, it has some chance of
success in Gentoo Prefix :)

Actually, there is no 'stable' concept in Gentoo Prefix. You are
always using latest version of packages. The Gentoo Prefix team simply
does not have the staff to maintain different stable/unstable trees.
It normally works out pretty well by leveraging some of the work of
Gentoo Linux developers and rely on the fact that massively broken
packages do not appear in ~arch on a often.

Hard to say the problem with the latest version. Did you look at the
bug tracker or file an issue?

If you have successfully bootstrapped, you actually have several
packages installed :)

Hope that helps a little bit,
