pnetc must be upgraded to 0.8.0 version otherwise will create the infinite upgrade-downgrade loop... !!! Multiple versions within a single package slot have been !!! pulled into the dependency graph: ('ebuild', '/', 'dev-dotnet/pnetlib-0.7.4', 'merge') pulled in by ('installed', '/', 'dev-dotnet/pnetc-0.7.4', 'nomerge') ('installed', '/', 'dev-dotnet/pnetlib-0.8.0', 'nomerge') pulled in by ('installed', '/', 'dev-dotnet/ml-pnet-0.8.0', 'nomerge') 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. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook.
Upstream hasn't released pnetc-0.8.0 yet.
