I don't know really but I believe that the problem is in the configure
script. Setting --with-libidn2 makes configure search for idna.h when
it should search for idn2.h. I tried using --with-libidn=no without
setting --with-libidn2, that makes configure search for idn2.h after
it finds libidn2. --with-libidn2 disables search of idn2.h for me at
least. And for me it is the same behavior of I call ./configure
directly as if I run bmake configure. You can try to have
--with-libidn=no in options.mk instead of
--with-libidn2=${BUILDLINK_PREFIX.libidn2} and see how that works.
I know its a little backwards to have the idn option turn of libidn but
it seems to work.
