pangomm & libreoffice error

[joachin]

Hey guys, having some problems trying to install pango mm:

pangomm

and libreoffice-bin:

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

NOTE: Use the '--verbose-conflicts' option to display parents omitted above

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

Thanks!

Same problem here. I remove boost which I think I don't need for the time. Thus, `hunspell` remains to be resolved.

emerge -av app-office/libreoffice-bin

These are the packages that would be merged, in order:
