Created attachment 362262 [details, diff] patch to add missing include Probably due to some cleanup in the C++ header files, dev-libs/liborcus-0.5.1 does not compile with gcc-4.8.1: The file src/orcus_xml_main.cpp is using some iostream(s) without including the appropriate <iostream> header file. I guess with some older gcc versions the erraneous code might work due to some other header file including <iostream> as some side effect. A patch fixing the missing include (and thus compilation with gcc-4.8.1) is attached.
Fixed in cvs. Thanks for report.
