how to build pgadmin3 when wxgtk was built with --disable-unicode ?

i built my wxgtk with --disable-unicode, because otherwise it uses the
bloated UCS4 format, and the option --enable-utf8only doesnt have any
effect (wx will still use UCS4).

according to a wxgtk developer, using --disable-unicode will work fine
with UTF8, which is usually used in linux.

now i'm trying to build pgadmin3-1.16.1.tar.gz:

configure: WARNING: unrecognized options: --disable-unicode
[...]
checking wxWidgets version... ok
configure: error: Your wxWidgets installation cannot support pgAdmin in
the selected configuration. This may be because it was configured
without the --enable-unicode option, or the combination of
dynamic/static linking and debug/non-debug libraries selected
did not match any installed wxWidgets libraries.

how can i patch the configure script/pgadmin3 that it accepts
--disable-unicode (which seems to be what other programs depending on
wxgtk provide) and i can get around past this build error ?

best regards,
