hrm, i looked in /usr/local/lib/erlang/lib and there's a wx-0.98.3 directory
(must be the version the latest macports version (R13B02) ships with? though
on my Snow Leopard machine "/usr/bin/wx-config --version" gives 2.8.8) but
all it contains are the directories doc, ebin, include, and src; "find
/opt/local/lib/erlang/lib/wx-0.98.3/ -name \*.so" gives no output.

do i take it that by commenting out "port:wxWidgets" from my erlang
Portfile's depends_build, I built erlang without wxwidgets?

Granted, that's not the same as disabling the whole thing altogether.

indeed! would still love to know if there's actual official support for
disabling wx/tk :)
