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.

page or refer to the Gentoo Handbook.

#
# Most of these packages provide a jce USE flag for those whom need the
# Java Cryptographic Extension Unlimited Strength Policy USE flag; whether that
# works depends from VM to VM, it seems to work for most except for the IBM VMs.
