GNAT on Mac OS X, need some help

[Achim]

Hello,

possibly this has been asked and discussed before but I can find older 
posts concerning this topic.

Since 6 month I'm using a MacBook running Mac OS X 10.6.6.
Till now I've just installed a few multimedia programs but no 
development tools.

Now I installed (or just unpacked) GNAT GPL 2010.
As stated in the readme, I gave ./doinstall and got the error message:

"The make command could not be found on your PATH. ..."

gps runs and gnatmake starts to work, but I think the "installation" is 
not as required.

So I think there are a lot prerequisites left out in the explanation 
that I need as a relative Mac newbe. I have the following questions:

1) What do I have to install (e.g. XCode Version?) for GNAT (including 
gnu/make) to become fully functional? I remember former posts stating 
that some GNAT versions are not compatible with some XCode versions or 
that GNAT has to be installed in certain folders to avoid inconsistencies.

2) Next, I need the posix binding (florist). As there is none on the 
libre site, can I just build the Linux version from sources?

less important:

3) I want to make gps a normal executable and connect it with all *.gpr, 
*.ads, *.adb files. When clicking on one of these files in the finder, 
gps should come up.

I've some experience using GNAT on different Linuxes and would be glad 
to hear, that you can work similarly on Mac OS.

Thanks for any help.
