Thanks your reply, so that lead me to create a new user and try it. It 
worked!
so ok i'm floored about that.
doing a diff with output of $set

the user where it worked has additional shell functions

make ()
{
.....
}
make_target_extract_script ()
{
}
and missing

LD_LIBRARY_PATH
pyenv ()
{
}
_pyenv_virtualenv_hook ()
{
}
I had tried previously with $unset LD_LIBRARY_PATH
and didn't help
I don't know the origin or? why one shell has the make() function....and 
works and where/when the other has it removed
or whether that is the actual problem
