rb_libtorrent depends on dev-libs/boost and needs dev-libs/boost to be built with theads. This results in the boost library files having a "-mt" suffix. The rb_libtorrent autotools configuration does not find these library files by itself, it needs instructions to find the suffixed files with switches like --with-boost-regex=boost_regex-mt. The configure script can handle it, the ebuild can't. Reproducible: Always Steps to Reproduce: 1. Emerge dev-libs/boost with the threads USE flag 2. Emerge net-libs/rb_libtorrent 3. Emerging fails Actual Results: The configure script dies with last messages: checking whether the compiler implements namespaces... yes checking whether the Boost::DateTime library is available... yes checking for main in -lboost_date_time... no configure: error: unable to find Boost.DateTime library, currently this is required. Expected Results: With the right configure script switches, configure will find all library files. There is an ebuild file for rb_libtorrent online created by on of the creators of the autotools configure script (me) at http://www.peerweb.nl/gentoo/net-libs/rblibtorrent/rblibtorrent-0.11.ebuild which demonstrates the use of extra switches to find the boost library files.
Right. Fixed, thanks.
