[gtkada] GtkAda on Mac OS X

[Nicolas Setton]

Hello John,

> cd GtkAda
> ./configure --prefix=/opt/local --with-GL=GL --with-GL-prefix=/usr/ 
> X11R6
> make
> make install

this is a pretty good achievement in itself :-)

our production environment at AdaCore is a bit different - we build  
for x86_64 and not x86, we are currently qualifying with Gtk+ 2.14.5  
and not 2.14.7 and, more importantly, we do not use Macports at all,  
(we build Gtk+ and all of the dependencies manually with our specific  
options), so we are not sure that any modification we make would be of  
use to you.

On the other hand, if you have a small patch to suggest to the  
configure (or, rather, aclocal.m4) or Makefiles in GtkAda that would  
save you from doing a manual build of the dylib, we would be happy to  
test it: if it does not break our regression testsuite, we'll apply it  
to the subversion tree and maintain it so that it works out-of-the-box  
with Macports.

Best regards,

Nicolas
