There are no ooo-3.0 in portage or in overlay :
emerge -va app-text/languagetool
These are the packages that would be merged, in order:
Calculating dependencies / * QA Notice: The 'hasq' function is deprecated (replaced by 'has') ... done!
emerge: there are no ebuilds to satisfy ">=virtual/ooo-3.0".
(dependency required by "app-text/languagetool-0.9.8" [ebuild])
(dependency required by "app-text/languagetool" [argument])
I have app-office/libreoffice-bin-3.4.3-r2 emerged here maybe it's a problem for languagetool ?
Ebuild removed from overlay. The LibreOffice extension is app-officeext/languagetool
Thank you Andreas.
