Weeeeird. I have no idea. The usual guess is that a partition is mounted 
noexec, but that would give an error. Or that the script is saved in DOS  
format, with CR-LF instead of LF endings, but that would throw a 'bad 
interpeter' error.

Try 'strace ~/bin/xyz' (emerge strace if you don't have it) and compare the 
output with your working machine, that should give some hints to what is 
happening.

What happens if you change the script to this?

#!/usr/bin/man bash

Oh, now I _do_ have an idea. What about startup files, like .bashrc, 
.bash_profile and such? Any recent chanegs here? Try:

#!/bin/bash -i

This forces the shell to be interactive, so it sources other startup files. 
Add 'xv' (bash -ixv) to let bash output which lines are being executed.
 Also put some debug info in .bashrc, .bash_profile, /etc/bash/bashrc, 
/etc/profile to see what of them is being started.

And try another user without your personal startup files. Same effect?
