The build system has hard coded stuff like -lboost_system-1_35. The ebuild adds -lboost_thread -lboost_date_time to LIBS, which results in a version mix for boost the libraries, resulting in undefined references, if another boost version then 1.35 is eselected. See build.log. See [1] for a workaround to make it always use boost-1.35.

Created attachment 211804 [details, diff] fix boost detection The problem here is that the configure script doesn't properly detect boost. I tries to search for newer versions too, but doesn't find them. So lets help it.
Thank you for your report and your patch. I am going to have a look at this bug but I am wondering if we shouldn't directly patch the configure script and send the patch upstream.
It looks like btg is compiling with boost-1.42 but it is failing when there is two boost versions installed in the system.

If so, please attach the log.
Actually, I have 1.42 and 1.41. When I am compiling, the configure script is recognizing 1.41... It should be 1.42. rb_libtorrent is compiled against 1.42 too.

If the configure scripts checks for the static instead of the shared lib the test fails.
Removed from tree wrt #326645.
