The ebuild commoncpp2-1.3.1 (latest stable) depends only on libxml2 but not on a special version. As I got an error about missing references I updated the libxml2 and it works. My Versions: dev-libs/libxml2 selected: 2.6.15-r1 doesn't work protected: 2.6.20-r2 work (on another box it is 2.6.19 and it works) So I would change the ebuild: workstation commoncpp2 # diff commoncpp2-1.3.1.ebuild.old commoncpp2-1.3.1.ebuild 14c14 < DEPEND="xml2? ( dev-libs/libxml2 )" --- > DEPEND="xml2? ( >=dev-libs/libxml2-2.6.19 )"
Thank you for the report. Fixed.
