 and Mac OS X.

 These executables are just that, executables.  There are no headers, thus
 the library binary is not usable in other projects.  As stated on the
 kakadu download page: they are for demonstration purposes.

 money to do anything under any circumstances.

 As I've also said, it's not a question of accepting money (I can't), it's
 a question of skill - I'm not a C++ programmer.  I can poke and prod, and
 have a fair chance of figuring out problems, but this one is too deep for
 me.

 Anyways, I wrestled a little more with the ECW library (poking and
 prodding), which includes its own custom JP2 library.  ECW on OSX has
 always been a troublemaker - getting it working at all, getting it working
 for universal OSX, getting it working in 64bit OSX.  Up until now, all I
 had working was ECW read-only, universal/64bit.  At one time the ECWJP2
 was working, but it broke a while back.

 I just got ECWJP2 working again, but only in 32bit Intel OSX (I can't test
 PPC right now, but it likely also works).  This is OK for Qgis, as 64bit
 Qgis on OSX is possible but still needs testing (and probably work).
 There are no color problems with Greg's test JP2 image using the ECW JP2
 library.

 I'm working with GDAL 1.6 right now.  I can't get the ECW plugin to load
 in GDAL 1.5 for some reason.  My current Qgis uses GDAL 1.5, and I'm
 waiting for GDAL 1.6 to finalize this coming week.
