Problems installing/running AdaCore GPS (GPL) in Mandriva 2009

[Anonymous <anon@anon.org>]

Hello,

I'm new to Ada and I'm having some difficulties with GPS.
I've downloaded the GNAT x86_64 package for linux from AdaCore's webpage.

When I try to install it (as root) the script (doinstall) runs 
apparently ok, with the exception that it complains about "unable to 
execute binary" for one of the tools.

The installation process continues and appears ok. However when I try to 
execute gnatmake or gps or any other tool I get the same error "unable 
to execute binary". I'm using Mandriva 2009 x86 64bits. Have any of you 
guys had this issue?

Are there any good alternatives (when it comes to IDE) to gps (if I 
can't get that to work)? KDevelop does not install correctly either, but 
I might be able to get around that. I know of the eclipse solution, but 
I'm somewhat reluctant to try that (for no good reason at all).

Regards,
Newbie.
