The folder /usr/share/pari-2.3.4/doc/ is deleted by the ebuild. This folder has files used by the online help system of the gp program. Code in ebuild that remove the folder: #remove superfluous doc directory rm -fr "${D}/usr/share/${P}/doc" || \ die "Failed to clean up doc directory" It`s wrong. It will break with the online help. To fix the problem, just remove or comment the lines above. Reproducible: Always Steps to Reproduce: 1. USE="doc" emerge pari 2. open gp program 3. type ??+enter Actual Results: The gp/gphelp can't find the help files. Expected Results: By default, it should show a dvi file.
Fixed in cvs. Thanks for the report.
