- WANT_AUTOCONF goes *before* inherit, not after - WANT_AUTOMAKE is unset, set it to "none" if automake is not required for this to compile - once the above is done, >=sys-devel/autoconf-2.59-r4 can be dropped from DEPEND, also WANT_AUTOMAKE=2.5 can be dropped from src_unpack(), autotools.eclass takes care of this
Fixed correctly in apache-2.2.3-r2, thanks for reporting! Best regards, CHTEKK.
