That won't change.  From source nothing changes.   It's just that you need to
build the gdal ecw plugin to get ECW support and you need the SDK for that -
and that's the same as on Windows and Linux.

For debian for instance there's also no ecw binary - the available package that
has a script that builds the plugin for you, if you tell where you SDK is.

Those won't help as they are probably not build with VC10 and are therefore
incompatible with the GDAL build (interface ECW<=>GDAL is C++; so unlike C the
ABI is an issue).

In OSGeo4W the ecw package was already tagged obsolete.  For the standalone we
could add a big fat notice...
