Damn! it was that simple.

chmod a+x /lib/ld* fix it. My hello.dyn and gnuplot now work.

I posted quite some time back in another thread that all my libs were 
without x perms and it got no comment. So I assumed that it was normal 
and the it was regarded as a dumb question.

So the question is: why is it installed with the wrong permissions?

I have just rebuild the toolchain and the perms look correct in sys-root.

3317406 -r-xr-xr-x 1 prof users  160750 2009-06-10 01:49
3317408 lrwxrwxrwx 1 prof users       9 2009-06-10 01:49 

However ldd still does not work:
# ldd gnuplot
-sh: ldd: not found
# which ldd

I think what may have happened it that , having noted that nothing had x 
in /lib I added it to all libs without noting that ld was (possibly) 
already executable. When I did not get any comment on that I likely 
reverted everything including ld to -x .

I'll do more thorough testing tonight but initial evidence suggests that 
it is fixed.

It would be good to have ldd as a tool but I think that is a differenct 

It tool a long time to find something so simple but at least I can 
rebuild everything dynamic now.

Many thanks, Peter.
