Hi, I have freetype 2.9 installed on my system, howewer I had problems with wine, and I found that older wine versions don't work with newer freetype (>2.8 ). So I masked 2.9, unmerged it and installed 2.8, but when I upgrade world packages still wants to pull in 2.9 and it asks me to unmask it, how to solve?

Post full output of emerge world and add also -t option.
Probably you have a installed package that require freetype 2.9

Code:
[ebuild     U #] media-libs/freetype-2.9:2::gentoo [2.8:2::gentoo] USE="X adobe-cff bzip2 cleartype_hinting png -bindist -debug -doc -fontforge -harfbuzz -infinality -static-libs -utils" ABI_X86="32* (64) (-x32)" 0 KiB

Total: 1 package (1 upgrade), Size of downloads: 0 KiB

The following mask changes are necessary to proceed:
 (see "package.unmask" in the portage(5) man page for more details)
# required by app-text/ghostscript-gpl-9.21::gentoo
# required by net-print/cups-filters-1.20.3::gentoo[postscript]
# required by net-print/cups-2.2.7::gentoo
# required by app-emulation/wine-vanilla-2.0.4::wine
# required by @selected
# required by @world (argument)
# /etc/portage/package.mask/freetype:
=media-libs/freetype-2.9

NOTE: The --autounmask-keep-masks option will prevent emerge
      from creating package.unmask or ** keyword changes.

I identified the packages that were causing the problem, fontconfig and pango, so I marked all stable, but the latter gives this error when emerging

Pango unstable not require fontconfig-2.9
pango-1.42.0.ebuild:
        >=media-libs/freetype-2.5.0.1:2=[${MULTILIB_USEDEP}]

In my mind, Portage could have greatly simplified your problem. In my opinion, your issue comes from a misuse of emerge.
I believe that Portage may manages downgrades but its database is not updated during a manual uninstall.

@fedeliallalinea: I would rather have chosen --autounmask-keep-masks as suggested.

Conclusion: The documentation should be clearer, more precise and a user should test emerge options.
