How could I solve the following problem? I 've obviously consulted http://wiki.gentoo.org/wiki/Troubleshooting and some other posts but they did not help.

I get:
Code:

# emerge -uvDN @world

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

dev-libs/libxml2:2

  (dev-libs/libxml2-2.9.1-r4::gentoo, ebuild scheduled for merge) pulled in by
    dev-libs/libxml2:2[!icu?] required by (dev-qt/qtwebkit-4.8.5::gentoo, installed)

  (dev-libs/libxml2-2.9.1-r4::gentoo, installed) pulled in by
    dev-libs/libxml2:=[icu] required by (www-client/chromium-38.0.2125.101::gentoo, ebuild scheduled for merge)


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.


Any ideas?

Thanks!


EDIT: thanks to IRC and the help of bonsai????? I resolved it after I understood that It should be a USE flag issue. Apparently, the
Quote:
/etc/portage/make.conf
flags are superseded by the
Quote:
/etc/portage/package.use
flags. In the first I had:
Code:
 USE="...icu..."
In the second:
Code:
dev-libs/libxml2 icu
But 2 pages above I had
Code:
dev-libs/libxml2 -icu
(!!) So, I removed the
Code:
dev-libs/libxml2 -icu
line and now it works.

PS:
Code:

#  emerge --info ; emerge --pretend --update --verbose --deep --newuse @world
