gnat on linux (strange problems and behaviour)

[brian <brianc@billybob.demon.co.uk>]

I read with interest the postings a few weeks ago where problems were
encountered with running
Gnat on Redhat Linux.
I have just upgraded to Slackware 2.2.6 from 2.0.36.
I seem to have run into problems reinstalling gnat and getting it to
work satisfactory.

1)  I am using gnat-3.11p-i686-pc-linux-gnu-bin ( but have also tried
the other libc1 version)
2)  I cannot even get the script doconfig to work.
It complains
bash: doconfig: command not found

(permissions seem ok)
if I do a "sh doconfig" I get this
doconfig: syntax error near unexpected token `$<'
doconfig: doconfig: line 28: `set x = $<'

3) So I just did a "make"
and all seemed well.
However I cannot get even the simplest executables to run from the
command line in a xterm.
I have to run them from the grasp window  (grasp is the editor I use to
code programs) to work.

Even executables I compiled before the upgrade are having this trouble.
Could I be missing something really basic? Is the problem related to
using the "make" command
and bypassing the doconfig/doinstall step? A problem with the KDE
desktop which is new to me?

Any help greatly appreciated
Regards
Brian
