The package is using pkg-config for it's libraries: /usr/lib64/pkgconfig/ini_config.pc /usr/lib64/pkgconfig/ref_array.pc /usr/lib64/pkgconfig/collection.pc /usr/lib64/pkgconfig/dhash.pc /usr/lib64/pkgconfig/path_utils.pc So all these are unnecessary, even with USE=static-libs: /usr/lib64/libini_config.la /usr/lib64/libref_array.la /usr/lib64/libcollection.la /usr/lib64/libdhash.la /usr/lib64/libpath_utils.la Should be using the 'all' argument in remove_libtool_files() from autotools-utils.eclass (See also bug 382541)
It might be good idea to ensure "Libs.private: " is properly set in .pc files before proceeding for static linking. Or if upstream has left it out on purpose, stating static linking to ding-libs is not supported, perhaps --disable-static unconditionally is in order. Or if upstream defaults to --enable-static, then patch to configure.{ac,in} is in order to pass AC_DISABLE_STATIC or LT_INIT([disable-static]) when initializing libtool: http://www.gnu.org/software/libtool/manual/html_node/LT_005fINIT.html
Fixed in tree, thanks for report.
