All versions of app-text/htmltidy currently in portage (3.10.29, 4.8.6, ~5.10.26-r1) abort during configure with. ./configure: line 1301: syntax error near unexpected token `tidy,$LIBTIDY_VERSION' ./configure: line 1301: `AM_INIT_AUTOMAKE(tidy,$LIBTIDY_VERSION)' This can be fixed (at least for 4.8.6) by changing WANT_AUTOCONF=2.5 to WANT_AUTOCONF=2.9 in the ebuild. (2.6-8 don't work). The DEPEND line needs to be changed too of course.
