When running osgconv --formats (that command will be available with USE flag "osgapps"): the following will be visible among all the formats listed: Warning: dynamic library '/usr/lib64/osgPlugins-3.6.5/osgdb_resthttp.so' exists, but an error occurred while trying to open it: /usr/lib64/osgPlugins-3.6.5/osgdb_resthttp.so: undefined symbol: _ZTIN5boost6detail16thread_data_baseE Reproducible: Always Steps to Reproduce: 1. (once) emerge openscenegraph with USE flag osgapps 2. run osgconv --formats | grep Warning Actual Results: Warning: dynamic library '/usr/lib64/osgPlugins-3.6.5/osgdb_resthttp.so' exists, but an error occurred while trying to open it: /usr/lib64/osgPlugins-3.6.5/osgdb_resthttp.so: undefined symbol: _ZTIN5boost6detail16thread_data_baseE Plugin /usr/lib64/osgPlugins-3.6.5/osgdb_resthttp.so not found. Expected Results: The plugin should be successfully listed like all other plugins before and after, eg.: Plugin /usr/lib64/osgPlugins-3.6.5/osgdb_lwo.so { ReaderWriter : Lightwave Object Reader {
