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