>>> Installing (8 of 23) sci-libs/netcdf-cxx-4.2-r300
 * This package will overwrite one or more files that may belong to other
 * packages (see list below). You can use a command such as `portageq
 * owners / <filename>` to identify the installed package that owns a
 * file. If portageq reports that only one package owns a file then do
 * NOT file a bug report. A bug report is only useful if it identifies at
 * least two or more packages that are known to install the same file(s).
 * If a collision occurs and you can not explain where the file came from
 * then you should simply ignore the collision since there is not enough
 * information to determine if a real problem exists. Please do NOT file
 * a bug report at http://bugs.gentoo.org unless you report exactly which
 * two packages install the same file(s). See
 * http://wiki.gentoo.org/wiki/Knowledge_Base:Blockers for tips on how to
 * solve the problem. And once again, please do NOT file a bug report
 * unless you have completely understood the above message.

Which USE do you have set for sci-libs/netcdf? It is unreproducible here.
