That's what I did to observe the behavior:
If I insert "echo AAA" at the beginning of /usr/bin/easy_install,
running easy_install displays "AAA" as the first line of output.
However, when I remove "echo AAA" from the beginning of easy_install
and insert an exit statement right after the first line--
#!/usr/bin/python
exit('BBB')
as well as an exit statement right after the first line of
easy_install-2.5 (I meant to say 2.5 before)--
#!/System/Library/.../Python
print 'CCC'
running easy_install displays "CCC" rather than "BBB". So the
interpreter seems to have jumped from the first line of easy_install
to the beginning of easy_install-2.5 -- without executing the second
line of easy_install.
