Description Martin Pohlack 2004-10-25 04:45:17 UTC

When I try to emerge preview-latex, a dependency to emacs is created, even if xemacs should suffice.

Reproducible: Always
Steps to Reproduce:
1. emerge unmerge emacs
2. emerge xemacs
3. emerge -p preview-latex

Actual Results:  
[ebuild  N    ] gnome-base/gnome-desktop-2.6.2
[ebuild  N    ] app-editors/emacs-21.3-r3
[ebuild  N    ] app-emacs/auctex-11.53
[ebuild  N    ] dev-tex/preview-latex-0.8.1 

Expected Results:  
[ebuild  N    ] dev-tex/preview-latex-0.8.1 

I removed all the emacs deps. in the ebuild manually and could emerge preview-latex

Yes, you need either emacs or xemacs, but portage
cannot handle dependencies relative to your system.
Portage is only able to process USE flag based conditional
dependencies, and you need to turn on xemacs USE
flag to get preview-latex for xemacs installed.

emerge -pv preview-latex

shows you that preview-latex has emacs and xemacs
USE flags.
