The einfo of the ebuild instructs user to install the fonts bundled with plotutils manually. I had a look into the distribution archive and I think the ebuild should rather tell the user the truth: plotutils-2.5.1/fonts/pfb/ completely overlaps with media-fonts/urw-fonts-2.4.6 plotutils-2.5.1/fonts/pfb/ get partly overlapped by media-gfx/swftools-0.8.1 (bug #256084) Fix the einfo() lines to instruct user to install media-fonts/urw-fonts directly. Leave in the hint about /usr/share/doc/plotutils-2.5.1/INSTALL.fonts.bz2 (append the .bz2 to the current einfo() contents).
I forgot to add fonts probably not covered by any other Gentoo package and what should be highlighted by einfo() and present in plotutils package: plotutils-2.5.1/fonts/pcf/tekfont?.pcf (4 font files) plotutils-2.5.1/fonts/bdf/tekfont?.bdf (same 4 fonts)
I fixed this in plotutils-2.6 that I just added to CVS.
